'Every year the shearwaters come to roost on Big Dog island. And every year Phoebe and her family come to hunt the birds. Phoebe loves the simple rhythms of her family's life on the remote island. But this year her attachment to Dusky, a baby shearwater, will change the way she sees life and her place on the island. As the time comes for the birds to migrate once again, Harry, Phoebe's closest friend, also leaves the island, to go to war. When the seasons change, and Dusky returns to his nest, Phoebe discovers that life has a grander scope beyond anything she had imagined.'
