Kira Walker has found the cure for RM, but the battle for the survival of humans and Partials is just beginning. Kira has left East Meadow in a desperate search for clues to who she is. That the Partials themselves hold the cure for RM in their blood cannot be a coincidence—it must be part of a larger plan, a plan that involves Kira, a plan that could save both races. Her companions are Ava Demoux, an unhinged drifter and former employee of ParaGen, and Samm and Heron, the Partials who betrayed her and saved her life, the only ones who know her secret. But can she trust them?The second installment in the pulse-pounding Partials saga is the story of the eleventh hour of humanity's time on Earth, a journey deep into places unknown to discover the means—and even more important, a reason—for our survival.
