Fans of Lauren Oliver and Gayle Foreman will be captivated by this YA psychological mystery that explores the cutting-edge science of fear.   Kelsey has lived most of her life in a shadow of fear, raised to see danger everywhere. Her mother hasn’t set foot outside their front door in seventeen years, since she escaped from her kidnappers with nothing but her attacker’s baby growing inside her—Kelsey.   Kelsey knows she’s supposed to keep a low profile and stay off the grid for their protection, but that plan is shattered when her dramatic car accident and rescue by volunteer firefighter and classmate Ryan Baker sparks media coverage.   A few days later, she arrives home to find her mother missing. Now, to have a chance at a future, Kelsey will have to face her darkest fears. Because someone is coming for her. And the truth about the past may end up being the most dangerous thing of all.
