Mara’s island home is drowning, slowly but surely, beneath storm-tossed waves. As the icecaps melt, the Earth is giving up its land to the ocean – and a community, a way of life, are going to die. But Mara has seen something extraordinary: far out among the dizzying electronic information stacks of the Weave, there are hints of a New World – of cities built out of the sea and reaching high into the sky. Cities where desperate refugees can surely find safety. In a terrifying gamble for survival, Mara and the islanders of Wing take to their boats in the ultimate exodus. Somehow they must find a new home in a world they no longer understand – a world where anything and everything is possible.

Mara’s epic quest becomes something even greater. An extraordinary journey into humanity’s capacity for good and evil. And a heart-wrenching story of love and loss and the triumph of the will to survive.
