Tony Abbott (2006)
A 7th grade boy's world is shaken up by a new student who was horribly disfigured in a fire. He seems to be the only person in the class who is aware the girl may have feelings, and when his best friend rejects being kind to her the boy finds the courage to be her friend and face what happened to her.
Short book, a bit emotional, the main character spends most of last quarter of book crying, but good for discussions on injuries, disabilities, accidents, making the "different" kid feel welcome. The ex-best friend has issues to explore too, plenty of reasons shown why he acts the way he acts.
