Twenty teens. Abducted. To play a game of man hunt.

Delaney Escott lives in a world where popularity reigns supreme. If you want to be noticed, social status is everything. The government is run by the Superiors: a very exclusive group of individuals who are virtually flawless. They are smarter than us and stronger than us, and to join their ranks is the highest honor. The Superiors pay an annual visit to the top schools in the nation and evaluate the students, choosing one boy and one girl - the most Popular in the school - to go the Capitol and train for Superiority. Delaney thinks that she's the only one indifferent to (and perhaps even suspicious of) the Superiors, until Caleb Payne, the most popular boy in school, approaches her with a request. He has a task for her, one that he believes she is uniquely capable of completing. And as she helps him, Delaney discovers that the government is hiding many secrets - and that the truth of the Superiors is far from what people believe it to be.

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.
