Zack and Lara have superpowers. Luke has new school shoes and a burning sense of resentment. He KNOWS that aliens disguised as gym teachers are about to attack Earth but will anyone listen? No. So one dodgy pact with a self-styled supervillain later, and Luke is ready to save the world. He just needs to find his trainers.

My Gym Teacher Is an Alien Overlord is the action-packed sequel to the bestselling My Brother Is a Superhero, winner of the Waterstones Children's Book Prize and the British Book Industry Awards Children's Book of the Year.

"...an extremely funny book... Full of satirical allusions, quips, comic dialogue and surprises in prose and plot, this irresistible entertainment reminds us that everyone looks like a superhero from the outside, but inside they are all worried about the same things, and that goodies and baddies are not all that clear-cut." - The Sunday Times

"This is a funny, sweet, surreal and madcap adventure. It s a 'sort-of sequel' to My Brother is a Superhero, but you don't need to have read that to feel involved." - BookTrust

"My Gym Teacher is An Alien Overlord, the second book in the My Brother is A Superhero (these titles!) series, reminds me a lot of Louise Rennison at her best. Though it's written for a younger audience, My Gym Teacher has that similar sense of heart. It revels in its space and it's bright, swift and deeply, genuinely, funny." - L. H. Johnson, Did you Ever Stop to Think and Forget to Start Again?
