The Yellowstone super-volcano nearly wiped out the human race. Now, almost a year after the eruption, the survivors seem determined to finish the job. Communities wage war on each other, gangs of cannibals roam the countryside, and what little government survived the eruption has collapsed completely. The ham radio has gone silent. Sickness, cold, and starvation are the survivors' constant companions.
When it becomes apparent that their home is no longer safe and adults are not facing the stark realities, Alex and Darla must create a community that can survive the ongoing disaster, an almost impossible task requiring even more guts and more smarts than ever — and unthinkable sacrifice. If they fail . . . they, their loved ones, and the few remaining survivors will perish.
