Sand. A hostile world of burning sun.Outlines of several once-busy cities shimmer on the horizon. Now empty of inhabitants, their buildings lie in ruins.In the distance a group of people—a family—walks toward us.Ahead lies shelter: a “shuck” the family calls home and which they know they must reach before the light fails, as to be out after dark is to invite danger and almost certain death.To survive in this alien world of shifting sand, they must find an object hidden in or near water. But other families want it too. And they are willing to fight to the death to make it theirs.It is beginning to rain in Fairfax County, Virginia, when McKenzie Strathie wakes up. An ordinary teenage girl living an ordinary life—except that the previous night she found a sand-lizard in her bed, and now she’s beginning to question everything around her, especially who she really is ...Two very different worlds featuring a group of extraordinary characters driven to the very limit of their endurance in a place where only the strongest will survive.
