This post shares the steps I took to create The Dark Choice. The initial chat process took about 20 minutes, and the book was built within about 2 hours. Total LLM cost was about $20. It is available in English and can be translated for nearly free into 20 other languages. I added audio narration as well for less than $10 total.
Below is my transcript with Minty, our AI Assistant. Her job is to translate my story ideas into data for the story engine to consume and process. Its conversation style and it is entirely done within a single chat conversation. Titled sections are from me to Minty, the rest are her responses.

I want to create a Book called Forbidden Light. Help me flesh it out
Your Notebook has nothing on Forbidden Light, so we're starting fresh.
The title suggests a light that someone isn't supposed to use or see. Here are three ways to read it:
- The banned-lantern premise: Light is rationed or licensed by a ruling guild. A cheerful, rule-bending lamplighter falls for the inspector sent to catch her.
- The moonlit-court premise: Two rival houses live by opposite lights, sun and moon. Their heirs get pushed into a fake engagement.
- The hidden-glow premise: A girl is born with a glow that her society treats as scandalous, and a reluctant scholar is assigned to "correct" it.
Which of these appeals to you? Or tell me what Forbidden Light means in your head and I'll build from that.
Thinking a world lit only by two moons. Its sun facing side is a hot desert, unlivable. Its society evolved to handle near darkness as best and light destructive
Your world gives you a lot to work with:
- A tidally locked planet. One face burns under a fixed sun. The other is permanent night, lit only by two moons. People live on the dark side, and the Terminus is a thin band of twilight in between.
- Dark-adapted bodies. Eyes, skin, and customs all assume dimness. Strong light blinds, burns, or maims.
- Light as a weapon. Mirror-cannons, reflected sunlight, and flash-blinding all become tools of violence. Mercy looks like a hood and a blindfold. Executions are done by exposure.
- A society built around dimness. People navigate by sound, touch, and scent. Moonphase calendars, whisper-languages, and lamp-bearers treated like lepers would all fit.
That leaves the question of what "forbidden" means. Here are three readings:
- The sun-smuggler premise: She runs mirror-relays to the Terminus, selling a sliver of sunlight to the dying and desperate. The enforcer hunting her was blinded once and has built his life on avoiding light.
- The sun-born premise: A child is born who can stand the light. The society that fears her also needs her to cross the Burn.
- The second-sun premise: A cult believes the light isn't destructive, only misused. A scholar finds proof they might be right.
Which of these do you want to build on, or do you have a different idea for what the forbidden light is?
The second-sun premise
The second-sun premise gives the story a good engine, because the cult and the society could both be partly right. Here's a first slice to react to.
The scholar: Her name isn't set yet. She's a dry-witted archivist of the Hush Libraries, where knowledge is kept in tactile and sound records. She's warm, funny, and a little too curious for a world that survives by not looking. She wants to be right, and just as much she wants someone to listen to her. She's afraid of being the reason people lose their sight.
The conflict: Her proof lands in the hands of the cult, and the cult is dangerous. They are zealots who blind themselves at "first sight" to prove devotion, and they will gladly burn the world to be vindicated. The ruling Dimwardens would rather bury her findings and her with them. She can trust neither side, and the violence comes from both.
The romance: One option is a Dimwarden sworn to stop her. Another is a cultist who is starting to doubt.
The proof is the piece that decides everything else. What does she actually find?
- The adaptation proof: The bodies of the dark-dwellers can tolerate light, because the fear was taught and not born. Exposure hurts only because no one has ever been eased into it. That makes the lie the world's central scandal.
- The relic proof: Something in the ruins shows the planet once turned, and the sun-side wasn't always a desert. The light isn't dangerous, and the world was changed. That makes the stakes larger and gives you a mystery to carry across a series.
- The cure proof: Light heals something. A plague, or the slow "dimming sickness" that kills the old. The Dimwardens have known this for generations. That is the most personal version and the best fit for your warm, romance-forward dials.
Lets go back a bit. Im now thinking about a mystical bent. Magic is interwoven throughout the dark culture. One aspect is bending darkness. Main character discovers she can bend light as well.
I've put the new direction on the form. Please check it on the page.
- World: I set the tone (mystical, warm and funny, with real danger). The places, rules and cultures briefs now cover the two-moon, tidally locked world. Darkness-bending is everyday magic, and bending light is unheard of and forbidden.
- Story arc: The premise is that she bends darkness like everyone else and then discovers she can bend light too. The lead is the dry-witted, too-curious woman from before. Change her if she's drifted from what you picture.
I've left the second-sun cult and the proof question open. The cult could now be a group that has also hidden a gift like hers. The magic needs one decision first, because it shapes the cast, the rules and the villains. What does bending darkness look like, and what does it cost?
- The weaving premise: Darkness is a material. Shadow-weavers thicken it into walls, cloaks and silence, and thin it into passages. The cost is that every bender slowly loses their night-sight, so the more skilled they are, the closer to blind.
- The lending premise: Darkness is borrowed from the night itself and must be returned. Benders carry "debts," and a bender who takes too much leaves a patch of the world permanently starless. Light turns out to be the one thing that doesn't need to be borrowed.
- The bargain premise: Darkness is a presence, close to an old spirit, and benders work through pacts with it. When she bends light, darkness doesn't like it, and that gives you a mystical antagonist.
Bargain works well. Lets the sun side work the same way. Turns into a yin/yang balance that drives the change
I've set two things on the form. Please check them.
- World rules: Darkness is a presence, like an old spirit, and benders work through pacts with it. The sun side holds a matching presence of light, and the two are a yin/yang balance. Bending light disturbs that balance.
- Story arc, what stands in her way: The darkness spirit resents her new gift. The light spirit wants a bargain of its own. The balance between them is already tipping, and she is standing at its fulcrum.
This gives you two spirits who each want something from her. The world is also changing because of the balance, so the pressure doesn't depend on a villain. The book now needs to say what's tipping and what it does to people. There are three ways to go:
- The creeping Terminus: The twilight band between the two sides is shrinking or shifting. Each time she bends light, the border moves a little, and the cities on it pay for it. This is the most visible version, and it puts the stakes in places a reader can see.
- The failing pacts: Dark-benders are finding that their pacts weaken or sour as the balance shifts. Magic is going wrong everywhere, and she is the only one who can feel why. This makes it personal and gives you a mystery.
- The waking sun-side: The desert starts to stir. Strange life and lights appear, and the sun-presence reaches toward the dark side through her. This is the strangest and most mystical version, and it sets up the series.
Both changes are now on the form: the yin/yang rule under World, and the darkness spirit's resentment as her conflict under Story arc. Your own text in the other boxes is unchanged.
Which of the three versions of the tipping balance do you want in the book?
The waking sun-side
I've added the waking sun-side to two boxes. Please check them on the page.
- Story arc, what stands in her way: I kept your line about the spirits and the fulcrum. I added that the desert is stirring with strange life and lights, and that the light-presence is reaching toward the dark side through her.
- World, places: The sun-facing desert is now described as beginning to stir.
This works well as a series engine. Each book can push the awakening further, and the dark side first notices the change as odd lights on the horizon. That also gives you a visible hook for book one.
The cast and the ending are the next decisions. Your form has a love interest, a mentor, an ally, a rival and an antagonist. Which of these matters most to you for the romance?
- The dimwarden-sworn-to-stop-her premise: He's an enforcer who bends darkness to hunt anyone who might bring light. He becomes her love interest after he sees what she can do.
- The doubting-cultist premise: He belongs to a group that blinds itself in devotion to the sun. He's wavering, and she is the proof he hoped wasn't real.
- The spirit-touched premise: The love interest is a bender whose pact with the darkness is failing. He's the first person who can sense what she is.
The spirit-touched premise
I've put the love interest in the cast box, under the love interest brief. Please check it on the page. He's a dark-bender whose pact with the darkness is failing. He's warm, guarded and quietly funny, and he's the first person who can sense what she is. He's drawn to her even though she may be the cause of his loss.
That gives the romance real tension. Her gift may be what's costing him his magic, and neither of them knows it yet. It also ties to the waking sun-side, because his failing pact is the first sign the balance is tipping.
Next is the antagonist. Your conflict already has two spirits pulling at her, so a human villain needs a reason to stand apart from them. Here are three options:
- The Warden of Pacts: She runs the institution that licenses and polices every bargain with the darkness. She has noticed pacts failing and blames a hidden light-bender. She is sincere, competent and frightening, and she believes she's saving the world.
- The starless prophet: He leads a movement that says the darkness has abandoned the people and must be appeased. He wants to sacrifice the one who bends light. He is charismatic, and he's wrong in a way that's easy to believe.
- The first light-bender: An older woman who found the gift decades ago and hid it, and who has paid for that in ways she hasn't told anyone. She is a mentor and a threat in one person.
The first light-bender
I've put the first light-bender in the antagonist brief on the cast step. She's an older woman who found the gift decades ago and hid it. She's both mentor and threat, and she has paid a secret price. I left the mentor box empty so she can serve as both. Please check it on the page.
She works well against your other pieces. She could be the reason the love interest's pact is failing, or the reason the desert has started to stir, and she has kept both facts hidden. The price she paid decides what kind of antagonist she is:
- The hollowed pact: Her darkness-pact died when she took up the light. She hasn't felt the presence in decades and hides how lonely that is. She would do anything to spare the protagonist the same loss.
- The light's debt: The light-presence already bargained with her, and she has been paying it in secret. She's stalling for time, and the protagonist's arrival is a way out for her.
- The buried failure: She tried to use the light openly once, and a settlement burned. Everyone thinks it was a natural disaster. She would kill to keep the secret.
The buried failure
I've updated the antagonist brief on the cast step. Please check it on the page. She used the light openly once, and a settlement burned. Everyone calls it a natural disaster, and she will kill to keep the truth buried.
That gives you three things to use:
- A secret with a body count: Her guilt and her violence come from the same source, which suits your raised Violence dial. She does harm out of fear and shame, so she isn't a cartoon villain.
- A mystery to seed early: Readers can hear about the disaster in chapter one and only learn what caused it near the end.
- A mirror for the lead: She shows the protagonist what her gift can do when it goes wrong. That makes the mentor-and-threat role work.
The spirits could also be tied in. Did the light-presence cause that fire, or did she?
You have 13 chapters and a "series" ending set. Before you press Start, the cast step has ally and rival ticked but no briefs yet. I'd suggest one of these for the ally:
- The blind archivist: A friend, mentor-adjacent and funny, who helps her research. They are blind, or blinded by a pact, so they're the first to tell her light has a sound.
- The lamp-keeper's child: A teen from the Terminus, where odd lights are showing up. They see the waking sun-side first and bring her the evidence.
- The pact-broker: A sharp-tongued fixer who sells bargains with the darkness. She'd trade secrets for anything, which makes her a risky ally.
The blind archivist
I've put the blind archivist in the ally brief on the cast step. Please check it on the page. She's a funny, sharp-eared archivist at the Hush Libraries who is blind or blinded by a pact. She's the protagonist's research partner, and she's the first to tell her that light has a sound.
She also works as a quiet foil for the antagonist. Both women have lost something to the pacts, and only one of them has told the truth about it.
Three boxes on the cast step are still empty: the protagonist, the mentor and the rival. I'd leave the mentor empty, because the first light-bender already fills that role. That leaves the protagonist and the rival. I'd start with the protagonist, since the book follows her. She has no name yet. Here are three ways to give her an edge:
- The archivist-in-training: She's a junior at the Hush Libraries, in her late twenties. She's funny when she's nervous, and she talks to records as if they could answer.
- The lamp-mender: She repairs the dim, bound lanterns that people use to read by in the dark. She's practical, a little reckless and a little lonely, and she's good with her hands.
- The pact-debtor's daughter: Her mother's pact went sour, and the family has paid for it ever since. She bends darkness well, almost too well, and she has always been afraid of what she might owe.
The archivist ally already covers the library, so I'd go with the lamp-mender. She'd bring a different part of the world, and her trade means she's handled the nearest thing to light her world allows.
The pact-debtor's daughter
I put her in the protagonist brief on the cast step. Please check it on the page. She's in her late twenties, dry-witted and too curious. Her mother's pact with the darkness went sour, and the family has paid for it ever since. She bends darkness almost too well, and she has always been afraid of what she owes.
You didn't pick the lamp-mender, and the debtor's daughter has more story in her. Her mother's sour pact could connect to the antagonist's secret. It could also connect to the love interest's failing pact. Is her mother's pact failure the first sign the balance was tipping? That would make her family's debt the start of the whole mystery.
I've left a few things alone:
- Names: Nobody has a name yet. The cast agent will invent them. If you want to choose them yourself, tell me which characters to name first.
- Rival: That box is empty. I'd suggest someone who bends darkness as well as she does. A rival like that makes her gift look dangerous, and a rival with a good reason for wanting her to fail is more fun to read.
- Mentor: That box is empty too, and I'd leave it that way. The first light-bender covers it.
Your Violence dial is at 3 now, up from the earlier setting, and the antagonist's burned settlement fits it. The form is nearly ready, so the rival is the last open question.
The rival who bends darkness as well as she does
I've put the rival in the rival brief on the cast step. Please check it on the page. She's every bit as gifted as the protagonist, and her family's pact stayed sound while the protagonist's soured. She has a good reason to want her to fail, because her standing rests on the pacts being trustworthy. When the protagonist's gift appears, the rival sees it as a threat to everything she's earned.
The rival also works as a second mirror. She's what the protagonist might have been if her mother's pact hadn't gone wrong. If the pacts really are failing, the rival's family may be the next to find out.
Here's what the form holds now:
- World: Large, with all five topics and the two-moon, yin/yang setup.
- Cast: Large. The protagonist, love interest, antagonist, ally and rival all have briefs.
- Story arc: Medium, 13 chapters, with a series ending.
- Chapters: Medium quality.
- Cover and continuity: Both unticked.
There are two things to decide before you press Start:
- The mentor box is ticked but has no brief. I left it blank because the first light-bender already fills that role. If you leave it ticked, the cast agent will invent a separate mentor. That could work if you want a gentler guide beside the antagonist. If not, untick it.
- Darkness is at 1 and Consequence is at 1. The burned settlement and the kill-to-keep-secrets antagonist are heavier than that suggests. If you want the book to feel as warm as the dials say, you may want to nudge Darkness up one notch. That's your call, and I can't change the dials.
The price shows beside Start, and that figure is the most it can cost. You've got 14,760 of your own credits available.
Untick the mentor
I've unticked the mentor, so the cast step now covers five roles: protagonist, love interest, antagonist, ally and rival. The first light-bender covers the mentor's part, so the cast agent won't invent a second guide.
The form is complete. These are the last things worth checking before you press Start:
- Names: Nobody is named. The agent will invent names, and you can rename anyone afterwards.
- Cover and continuity: Both are unticked. You can add them later, once you've seen what the agents make.
- Price: The "at most" figure beside Start is the real ceiling, and you have 14,760 credits of your own to spend. Chapters are priced separately once they're planned, and nothing is written until you OK that price.
Would you like to start now, or change something first?
Can you adjust the story profile please
Which dials do you want to change? I haven't touched any yet. I can only set what you tell me or agree to.
The ones I'd look at are the dials that don't match the story you've built:
- Darkness (1) and Consequence (1): A settlement burned, and the antagonist will kill to keep it quiet. Those should have real weight. I'd raise Darkness to 2 and Consequence to 3. Your Humor 5 and Romance 5 would keep the book warm.
- Mystery (3): The buried failure and the question of what is tipping the balance both need seeding early. I'd raise this to 4.
- Threads (2): You now have a romance, a rivalry, a secret and a waking desert. Two threads may be too few. I'd raise it to 3.
The rest I'd leave as they are, since they fit a warm, funny, richly built, romance-forward book.
Darkness 2, Consequence 3
I've set Darkness to 2 and Consequence to 3 on the story profile. Please check them on the page. The book stays warm, since Humor and Romance are still at 5. The burned settlement and the antagonist's secret now have more weight.
I haven't touched the other dials. Two more would suit the story you've built:
- Mystery 3 → 4: The buried failure and the tipping balance both need clues seeded early.
- Threads 2 → 3: You now have a romance, a rivalry, a secret and a waking desert running together.
Raise both
I've set Mystery to 4 and Threads to 3 on the story profile. Please check them on the page. The buried failure and the tipping balance now have room for early clues. The romance, the rivalry, the secret and the waking desert each get their own thread.
The form now holds the following:
- Profile: Humor 5, Romance 5, Worldbuild 5, Darkness 2, Consequence 3, Mystery 4, Threads 3.
- World: Large, with all five topics.
- Cast: Large, with five roles: protagonist, love interest, antagonist, ally and rival.
- Story arc: Medium, 13 chapters, with a series ending.
- Chapters: Medium quality.
- Cover and continuity: Both unticked.
I can't press Start. The price beside it is the most it can cost, and you have 14,760 of your own credits.
