Joshua's Island by Patrick Hodges
Joshua is small for his age. He has been bullied relentlessly for years, and all of his friends have drifted away from him. Eve is a pretty girl who has just been recruited into the popular clique. The two couldn't be more different.
As they begin their final year of middle school, the unlikely pair find themselves partners in Science class. At first reluctant to work with him, Eve soon discovers hidden truths about not only Joshua but their school that turn her world upside-down.
The two form a relationship that will teach them both the true meaning of friendship, loyalty, and love... a relationship that will end up changing not only their lives, but the entire complexion of their school.
