Tom's parents have taken a research job on an idyllic Pacific Island. It sounds great, but Tom's not enjoying it very much until he makes friends with Pero, who tells him of a strange tale regarding the singing caves. It seems that those who venture in, don't every come back. Tom dares Pero to go in and when he does and disappears, Tom holds himself responsible. Tom decides he must go into the cave either to find Pero or face whatever the caves might bring. Suggested level: primary, intermediate.
