For Aiden, Chloe, Ava and Josh, holidays at their grandparents' cottage mean wild beaches, no curfew, Bella the dog, and most of all adventure!While sailing their grandad's boat along the coast with her cousins, Chloe sees a terrified face at a tower window on Thorn Island. Could the face belong to recently kidnapped George, the only child of a rich local businessman? No one they tell believes there could be a child held prisoner in the tower. Certain that the villains are hiding out nearby, the cousins must use all their skills and cunning to conduct a daring rescue.
