The Mum Protector never lets Callum do anything other kids do. It's a miracle she's agreed he can attend his first ever school camp. He won't get to go if she finds out he's changing colour.

That's not the only weird thing happening since Callum found a strange object at the local quarry after their neighbour claimed a flying saucer chased him home. Lara, the oddball girl from school, is reading his mind, and now they have both been called on to help two stranded young aliens who want to get home.

Will Callum and Lara get their interplanetary visitors safely away from Earth before the Department of Off Planet Entries catches them?
