January is the epitome of boring—that’s what everyone told her. Subsob siya sa pag-aaral at walang social life. Hindi pa nga siya magkaka-Facebook kung hindi siya napag-trip-an ng pinsan niya! But if boring means she could focus on her dream—January is proud to be one Juan Luis is a big distraction. But maybe he’s everything she needs.

Seventeen-year-old April Parker wakes up in an underground facility, a shock bracelet on her wrist and a five-day countdown on the clock. Dozens of other teens share her inexplicable fate, but their unseen captors never intervene no matter how brutal conditions become. When the ruthless - and unnervingly magnetic - Marcus seizes control, April's trauma-forged instinct is to lay low. But protecting her friends drives her to bargain with the boy she should fear most - a boy whose reality fractures with every tick. Then the countdown ends, and the real terror begins. Powers ignite. Alliances shatter. And predators are born. And with a saboteur among them determined to keep the doors closed forever, escaping what comes next may be the only way to survive it.
