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.

"I need you," he whispered from the passenger seat. Why would I trust a bad boy? But I felt, for some reason, that I needed him to. I turned to look at him, but he was already leaning in to kiss me. Why is love so complicated? Maya Reeds is a seventeen year old girl thriving on independence and drive. She thinks boys are mindless, immature imbeciles and has steered clear of the entire concept of love in general. Her single mother is not just a role model, but an inspiration. Leaving for a business trip to China, Maya's mother has high ambitions for her future. However, she can't leave her daughter alone for all those months. That's where Carrie Groom comes in. Carrie has been friends with Maya's mom for years, and her home seems like a harmless place to stay for the duration of Maya's seeming abandonment. Never thought that Carrie could've raised a bad boy. As Maya endures this temporary move, she is sent into a whirlwind of desire, heated emotions, and betrayal- all fueled by the boy who lives just down the hall.
