SOLVED. YA Novel set in the 20's (I think) about a girl who was abused and whose father builds her a magic cinema where she gets trapped and lives a perfect version of life/relieves happy memories [s]

I read this book around 2012-14 whilst at school and have been thinking about it a lot recently. I can't remember the name of the aurthor or the title of the book at all, but I'm pretty sure the cover of the book was black and white/grey with maybe a close up of the mechanics of an old film camera as the cover pattern. My memory of the plot is pretty hazy too but the general gist is this:

There's a teenage girl living in a big house with her dad (who I'm pretty sure is alwasy busy with something, can't remember what, he might be a scientist), she may go to an all girls school or at least used to but kicked out for misbehaving?
There's definitely moments where she's back at home and she talks to the cooks son who is in love with her. At one point she reveals in a shed when the cooks son brings her ginger cake (which was her favourite, don't know if it was specifically ginger) that she was raped or abused when she was younger by someone older.
These two develop some kind of romance through out the book.
Later on it's revealed that her dad has built this giant old fashioned cinema for her at the bottom of their garden but when you enter it takes you to some kind of alternate reality that consists of her old memories or some kind of perfecf life that she's forced to live. Her dad does this to protect her.
Whilst she's in the cinema she doesn't age but everyone else does in the real world. The cooks son ages somewhat and decides he needs to save her from this cinema/memory prison. He enters and finds her somewhat clueless about her situation but helps her escape in the end.

I remember this book feeling quite summery and a bit like the very start of atonemnet in that kind of hazy, old fashioned vibe.
It may be set in america, again i can't remember.
The girl character in this might be called Violet.

Not knowing the name of this book has really been bothering recently so really hope this gets found!

Thanks!!

No sorry not the diviners or anything else by Libba Bray, but thanks for the suggestion!

I also think there's a scene from when she's at boarding school where she breaks out for a day and goes to the city with some guys, maybe a vicar?
