Books to heal a bullied young girl

Seeking help for an 11 year old girl in my life who is recovering from severe bullying from a classmate and is need of healing from it. I'm looking for YA fiction with strong characters that teach confidence and understanding for why people do bad things/hurt each other and how to put those things behind you. I think seeing another character survive and grow from adversity would help her feel less alone.

This is not body image related bullying, she would benefit from understanding cruelty with both confrontation and escapism. Her reading level is quite high for her age.

My first thought was The NeverEnding Story but I've only seen the movie. Maybe something like it but with a female protagonist? I don't think a redemption arc for the bully is realistic in this situation. Graphic novels are a plus.

She enjoys Nancy Drew Diaries, The Babysitter's Club, Bee and Puppycat and Kiki's Delivery Service.
