Rachel is 19. She doesn’t know how to handle her new stepmother, let alone the end of the world. But after finding her stepmother dead, Rachel is suddenly racing against time—and terrifying, unnatural forces—to survive a gruesome apocalyptic event. Outside her door, the college town of Fort Collins, Colorado, is filled with corpses, and something unfathomable is happening to those bodies. And it’s only just begun.

As Rachel struggles to comprehend her horrible new reality, she’ll need to find answers to questions she never thought she’d ask—all while desperately searching for her lost father, on whom she pins all her hopes for coming out of this phenomenon alive and intact. But nothing will be as it seems.
