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.

Two girls, two secrets, and a boy who will make them question everything they've ever believed. *** Roxy thinks that she is in control of everything: with flames flaring at her fingertips and an equally fiery attitude, what more could she need? But when Brae arrives in the Helian Realm and sets off a whirlwind of emotions, she starts to question if her life is really as perfect as she'd always believed - and if she can play her part in a plan that will send Brae back to the Arcan Realm as a pile of ash. Alone in the Arcan Realm, Jasmine has none of Roxy's confidence or intensity. But she does have a secret - and Brae - and she's not going to give either up willingly. {Fire, Water and Air are also available as ebooks from all online retailers}
