I'm reading your book Family, I will be honest when I read a chapter I get so mad at Ava's family.
I think you need to make Ava stronger she should just leave and see what will happen then.
I was thinking ava has cancer and works 3 jobs just to pay for the treatment and surgery she makes sure to wear a wig and that no one will find out she has a secret box full of money it gets stolen by one of her brother so ava starts to spend more time looking for another job and working ava's brother put a camera in her toom just to find out she is working 3 jobs and has cancer
