As Tom Hassler, Hope of the Sea People, races to an oil spill from a wrecked ship to help the terrified, oil-soaked birds, his mind is already on a holiday. Somewhere nice and warm. After all, his grandmother has promised - and he knows he's earned it. But when he finds himself on a tropical island with his best friend Lydia and an aunt he's never met, it all seems too good to be true. And it is. Just offshore is Illiya Island - Snake Haven, home to a secretive snake-worshipping cult. Mysterious giant saltwater crocodiles lurk, and when raiders strike, Tom must draw on every bit of courage and skill to save his friend from the evil snake-worshippers. But has he bitten off more than he can chew? This time, will courage be enough?
