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.

Reese Caldwell has a secret weapon - she talks with her dead twin brother. Together they hunt the scum of the earth, child killers and rapists, and take justice into their own hands. When a world renowned psychic medium unexpectantly enters Reese's life, she is confronted with hiding her secret and compelled to find her brother's long lost murderer.
