Maggie is imprisoned at Real Impact, a boot camp for troubled teens in the Mexican high desert, when she learns the outside world has been forever changed by the HORPOV-25 pandemic. Everyone and everything she once knew is dead. Guided by Abigail and her crew of "troubled" teens, Maggie embarks on a journey to discover what it means to survive in a terrifying new world—and in the process, finds a young boy named Valentino who is searching for home.

Meanwhile in California, Warren and April are heading south on a quest to find April’s biological son. They are joined by their newfound friend Damian and his dog, Wolf. Along the way, they find signs of a threat that may have deep ties to April’s past. And as they draw ever-closer to Valentino, their lives collide with Maggie’s in a way that will change their world and shape the future of humanity.
