For rentboy Nico Fernández, it's a simple job: seduce a presidential advisor to help cement approval to launch Project Juggernaut. He's done similar work for General Logan McClosky before, and manipulating people for his favorite client beats the hell out of being trafficked for slave wages in some corporate brothel.
Zach Houtman feels called to work with the most vulnerable outcasts of society. But his father, the Reverend Maurice Houtman, insists that Zach work for him instead as he runs for Senate. Zach reluctantly agrees, but is horrified to see his father leaving behind Christ's mandate of love and mercy and preaching malicious zealotry and violence instead. Zach even starts to suspect his father is working with fundamentalist terrorists.
When Project Juggernaut accidentally unleashes a deadly plague that claims billions of lives, Nico and Zach are thrown together, each bearing a burden of guilt. With only each other for safety and solace, they must make their way through a new world, one where the handful of people left alive are willing to do anything -- and kill anyone -- to survive.
