It's 2040, and 18-year-old Tiana admits to sleeping through most of her life. But Ben woke her up. How could he not? All those scars intrigued her. They may be an odd couple, but being cast as some sort of Romeo and Juliet never made much sense. They weren't bothering anyone. They were just having fun and saving the world for each other. Unfortunately, a car accident has a way of putting an end to fun and big dreams. When Tiana wakes up in the hospital, she finds herself separated from Ben by lost memories and strange circumstances. And the mysterious world is just about to get more mysterious. Without warning, the human race suddenly faces extinction when an inexplicable affliction takes the life of anyone who falls asleep (you sleep, you die). With the clock ticking, Tiana and Ben fight to reunite, desperate to seize as much life and love as time will allow. But these two are about to face an even bigger existential challenge. If love conquers all, it has one hell of a fight on its hands.
