Storme is still looking for this book from this past reader question (still unsolved), and she’s provided us with more details in case this might help!
She’s back again saying:
I’m back again hoping some new people will look at the post and help with a book I’ve been looking for so long!
The details that I remember-
The heroine’s name could be Echo though I’m not completely sure.
The h lives with her father and stepmother who physically abuse her. She is bullied in school because of the clothes she wears and her timid nature. The bullying at the school gets bad. The H who goes to the same school also says mean things to her like ‘Why does she even bother living and she should die’ something along this line.
