Luke Thorpe is a fifteen - year - old wimp. Excellent at maths and terrible at sport, he'd rather keep his head down and get on with his schoolwork. Yet, mysterious and uncontrollable changes in his behaviour and appearance - patches of hair growing rapidly, howling rather than singing the hymns in assembly, sudden growth spurts causing his clothes to rip off - are threatening to rocket him out of obscurity. Join Luke on a journey of discovery, embarrassing mishaps and hilarity as he gets to the bottom of his werewolf roots, joins a pack, and finds himself en route to war against the vampires (whose number include a rather wimpy, but familiar face)...
