"It is your choice," he said, stepping so close to me that our lips were almost touching. "Either do what I say - or get another job." My heart stood still as I gazed up into his deep, dark, dangerous eyes... In a world where women's only role in life is to sit at home and look pretty, Lilly is determined to fight for her freedom. There's only one problem: a powerful man blocking her way.

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.
