Alex, a resourceful 17-year-old running from her incurable brain tumor; Tom, who has left the war in Afghanistan; and Ellie, an angry eight-year-old, join forces after an electromagnetic pulse sweeps through the sky and kills most of the world's population, turning some of those who remain into zombies and giving the others superhuman senses.

An electromagnetic pulse flashes across the sky, destroying every electronic device, wiping out every computerized system, and killing billions. When it happens, Alex was hiking in the woods to say good-bye to her dead parents and her personal demons. Now desperate to find out what happened after the pulse crushes her to the ground, Alex meets up with Tom--a young soldier--and Ellie, a girl whose grandfather was killed by the EMP. For this improvised family and the others who are spared, it's now a question of who can be trusted and who is no longer human.

Author Ilsa J. Bick crafts a terrifying and thrilling novel about a world that could be ours at any moment, where those left standing must learn what it means not just to survive, but to live amidst the devastation.
