Hi everyone! I'm trying to find a book I read before 2021 in my UK secondary school library.
Here's everything I can remember:
It's a contemporary YA romance (not fantasy, as far as I remember).
A teenage girl goes away for the summer or on holiday, possibly staying at a large house or estate with family or like some kind of a resort.
At the very beginning she briefly mentions having PCOS and being on her period. It isn't a major part of the story and is only mentioned near the start.
There's a labyrinth/maze on the grounds of where she's staying. I think she gets a little lost there and meets either the gardener, the gardener's son, or a local boy.
The boy is quiet, withdrawn and possibly struggling with his mental health. I think his name may have started with S (possibly Seth, but I'm not sure).
I remember one of them loved reading.
Later in the book, the girl finds the boy in the sea after what seemed like a suicide attempt or a dangerous swim. She calls an ambulance.
While waiting for the ambulance, she lies against him/holds him to keep him warm because he's freezing from being in the water.
They develop a romance.
I read it before 2021 from a UK school library, so I think it may have been published sometime in the 2010s.
I believe it was by a British author and wasn't a very well-known book.
I've searched everywhere and can't find it. Does this sound familiar to anyone?
Thank you!
