Really want to find this book I read about 2 years ago in 2023 but no matter what I type online, I cant find it.
It is about:
Orphan girl taken in by rich family, Step brother (possibly called royce) is protective of step sister, they have a boat party and shortly after the brother leaves and joins a MC.
The step sister ends up getting abused by step father (sexually), the step father makes her join a club where she is to please people however they want. The step brother and his friend called Wicked end up having sex with her in one of the rooms, un aware it is her.
Step brother starts being more present in the girls life, becoming very protective of her again, where the step sister does alot to protest him in all he does.
She secretly is getting abused by a guy wearing a bunny mask where he hurts her with a pole and he sends it to the brother, step brother does not know it is her in the video.
The girl tries to shut down the organisation, with the help of Wickeds sister, who he thought was long gone and possibly dead.
The girl finds out her mother was abused by the same buy and she helps her shut down the organisation.
The MC that the brother is in becomes a home for the girl, where she finds out the MC president is her real father.
The MC president already has another daughter with someone from the club. The step sister becomes friends with the girl, helping her but is unaware she is her sister.
The dad recognises the girls mother and has only ever truly loved her.
