For seventeen-year-old Samantha Campbell, running back woods trails usually means freedom from her less-than-perfect life. That is, until the day a morning run turns into a living nightmare. When Samantha wakes up to find herself bound to a dirty, pinstriped mattress, she realizes she’s anything but free. With a masked abductor repeatedly injecting her arm with an unknown substance while holding her captive, Samantha tries in vain to find out what he wants, but he refuses to speak. Until the day he breaks his silence and his twisted words are worse than what she’d imagined. He promises her one day she will fall in love with him but the best part will be that she won't know who he is... until it's too late.

Finding herself freed from captivity, with her captor still at large, Samantha is on guard against everything and everyone around her. Unfortunately, walling up her heart proves difficult when eighteen-year-old Blake Knightley moves in next door. When Samantha starts experiencing strange changes within her, she realizes her captor may have left her more damaged than she originally thought. Now she must turn to Blake for help in order to unearth the truth behind the monster who started this all... or risk experiencing worse things than just falling in love.
