Mara's island home is slowly drowning beneath storm-tossed waves. As mighty icecaps melt, the Earth is losing its land to the ocean--and a community, a way of life, are going to die. In a desperate bid for survival, Mara and her friends set sail in the ultimate exodus. But Mara's quest will become something even greater--a journey into humanity's capacity for good and evil, and a story of love and loss.
