Floyd is a star of under-18s tennis. Since he was little, all he’s ever known is the routine of training, of the matches, of trying to be the best. But something strange is happening. A boy called Mike has started turning up–a boy no one else can see. He keeps appearing whenever Floyd is playing tennis and making him lose his game. Floyd needs to discover what Mike wants–and what that will mean for him, and where his life is headed. Floyd is at the start of a journey that will lead him into a headlong collision with his family, girls, friendship, and self-discovery.
