Exodus

Less than a hundred years from now, the world as we know it is slipping beneath the sea, and Mara's island home of Wing is next. But one night, in the ruined virtual world of the Weave, Mara meets the mysterious Fox, a fiery-eyed boy who tells her of sky cities that rise from the sea. Mara's only hope is to set sail on a daring journey to find a new life for herself and her friends, but awaiting her in the sky city is danger, a heart-wrenching love - and a battle for the future that will tear her world apart . . .
