it was about a girl who was kidnapped and had her legs cut so she couldn’t walk. she spent most of her time leaning against a wall with her legs bandaged. she has to have dinner with her captor and he gives her a book with messages from previous captives inside. she learns how to walk again to try to escape. i never finished it but I really hope someone can find it! it was relatively new (post 2015 I think)
