Aaron is a lonely, unloved boy when he first meets James. Their friendship seems like a dream come true—or perhaps just a dream, because no one else can see or hear James. Aaron stubbornly clings to his new friend, however, even when the friendship makes him an object of scorn and ridicule. No matter the years that pass, or the challenges they face, Aaron refuses to give up on his best friend—but life might just find a way to take James from him anyway.
