Eleven-year-old Brendan Doyle doesn't get along with his foster mother, he's failing fifth grade, and he's bullied mercilessly by a band of boys in his class. Then Brendan meets two potential friends--an eccentric old man and a girl from summer school--and he sees that there may be hope for him after all. No one is kind to sixth-grader Brendan Doyle: his foster mother, his teachers, his classmates, and especially the thugs who bully him. He takes refuge in books, drawing, carving, and daydreaming. When Brendan stumbles upon an old man near his tree house in the Virginia woods, he is quick to believe that this is the magical Green Man, guardian spirit of the forest. Brendan's need to immerse himself in his fantasy world becomes more acute, until he meets a girl with secrets of her own who may just keep his feet on the ground.
