The novel is about a boy called Measle who has been recently reunited with his parents, Sam and Lee Stubbs. On a day out they visit the Isle of Smiles, a theme park, and from then on things take a turn for the worse. Lee is captured by wrathmonks (warlocks that have gone mad) and taken to the Isle of Smiles. Sam has his memory wiped, and Measle and his dog, Tinker, are left to their own devices to find and rescue their parents. Once Measle reaches the Isle of Smiles, the wrathmonks cast a spell that causes all the creatures in the theme park to come alive and attempt to kill him. After he has successfully run away from the creatures, the wrathmonks catch him and want to kill him, but their leader, a dragodon, orders them to take him to a ride which leads into the dragon's lair. After a fight with the dragon and the dragodon, Measle and his mother escape and get back to their house where after a short fight the wrathmonks are defeated.
