Waiting for Gonzo by Dave Cousins
Things could be going better for Oz. He's just moved miles from all his friends. A prank at his new school puts him in the crosshairs of "Psycho" Isobel Skinner, a bully who also happens to be his mum's new best friend. And he's driven off the only other kid who will have anything to do with him: a Tolkien-obsessed boy in desperate need of a decent playlist. With his life careening out of control, Oz sets about making things right. But when he stumbles on his sister's game-changing secret, Oz is left wondering if he can ever get his old life back . . . or if he's stuck forever in this craziness.
