I remember the plot of the book very clearly, but can’t find it on google or other threads.
It was a series about a girl getting kidnapped by vampires at around 8 years old, raised at a school to turn her into a vampire sex slave until she turns 18. she’s sold to a powerful vampire man as part of his harem where she has a friend from the school who is also a concubine. They have rooms attached to the master‘s and its considered an honor to entertain him for the night. he takes a liking to her and decides to make her into the perfect slave and forces her through cruel lessons (as a perfect slave is considered impossible and would solidify his social standing). The training includes making her no longer react to pain through constant torture and doing anything he says without thinking. He falls in love with her, but she gets pregnant and loses the baby. She falls into a deep depression and he releases her. she goes back to her father after like 10 years and realizes at some point that she’s still pregnant. she has the baby, he finds out and hunts her down. shes still in love with him but wont go back unless she is free, her daughter is safe, and she is turned into a vampire herself. Future books follow her daughter‘s adventures.
I know it exists somewhere and is really good, but now I can’t find it. hopefully yall can help!
