After 37 years on a brutal and dangerous journey through space, a federation of settlers finally arrives on the planet Salt. Thus begins the colonization of this brave new world--a process that inevitably slips into a tragedy of biblical proportions. The two communities who undertook the voyage originally united in peace and a shared vision of a fresh beginning. Once isolated in a landscape of cruel majesty and minimal resources, however, ancient enmities begin to tear them apart. Related alternately by Petja, from the Alsist people, and Barlei (a Senaarian), their different voices, perspectives, and experiences come together to make an unusually rich and complex story about the fragility of life.
