In the viral labs of San Francisco Hospital, Dr. Kane Larson is creating a virus that will bring on the next apocalypse.
Ryan Brennan buys a cabin in the tiny town of Riverton to escape his family's fame. What starts as nothing more than a flirtatious glance compels him to enter the lottery. But his beautiful bride is more important to the world than he knows. She is the key to surviving the next apocalypse.
In a post-apocalyptic world where there is no government, men by the last name of Brennan represent the only justice. Reverently referred to as Brennanmen, they are tied by kin, guided by honor, and fueled by a need for justice.
