Gamer Girl by Marianne Mancusi

I enjoyed this Young Adult book - check it out at your local library

Maddy has left her private school in Boston for her grandmother’s unicorn statue infested house after her parents divorce. Her mom and her former friends are too busy, her sister can’t understand and grandma helped to get her labeled “freak girl” on her first day of public school. Her only escape from this reality is an online fantasy game where she falls for the dashing and gallant, Sir Leo. Through a few like minded souls and a new manga club, she begins to find a way to enjoy reality again and find her real life knight.
