When disaster strikes a school trip, Martine and her classmates are left fighting for their lives in shark-infested waters, until dolphins guide them to a coral-ringed island.

Here the castaways, at odds with each other, must learn to survive.

Will Martine's secret gift allow her to help both animals and humans when a deadly peril threatens them? And will those powers be with her when she needs them most?

Martine's courage and bushcraft skills are tested to the limits as, marooned in the ocean, far from home, she wonders whether she will ever see her beloved white giraffe again.
