Author Dan Wells is back with the sequel to the sci-fi blockbuster Partials. After discovering the cure for RM, Kira Walker sets off on a terrifying journey into the ruins of postapocalyptic America and the darkest desires of her heart in order to uncover the means—and a reason—for humanity's survival.

Dan Wells extends his richly imagined, gritty world and introduces new memorable characters in this second installment in the Partials Sequence.

Kira's journey takes her deep into the overgrown wasteland of postapocalyptic America, where she and her companions, including Samm and Heron, must navigate the dangers of a world on the brink of war. Meanwhile, back on Long Island, humanity is gearing up for a confrontation with the Partials, and Marcus knows his only hope is to delay them until Kira returns.

This pulse-pounding installment is the story of the eleventh hour of humanity's time on Earth, a journey into places unknown to discover the means—and even more important, a reason—for our survival.
