The Omnibus editions of Prepper's Crucible is a compilation of the first three books of the series. It begins when our group of preppers flee Phoenix, Arizona, in route to their ranch in Prescott, in the wake of an EMP that wipes out all power, transportation, and telecommunications networks. Once there, they hunker down until the threat of violence forces them to defend themselves and their neighbors. In a series of battles, culminating with and attack on the town by over 200 gang members, they manage to survive the first month following the EMP.
