Pippa and friends are off to a tiny tropical island for school camp - but what happens when their group are split up?

The students in class 5M are heading off to school camp. Pippa has never been away on camp before, at least not to a deserted tropical island! The Sassy Sisters look forward to five blissful days together exploring Shipwreck Island's beaches and lagoon. But when the teams get regrouped, Pippa has to learn to cooperate with Olivia and the other girls.

Mrs Marshall promised challenges and adventure, but she forgot to mention the pranks. After one too many of the boys' tricks, the girls decide to take their revenge.

Will class 5M survive Camp Castaway?
