Still healing from the break-up, introverted Megan reluctantly agrees to join her mother on a luxurious cruise to Mexico to rebuild her shattered world.

Meeting the charming Nate Talbert and embarking on a whirlwind ship romance convinces Megan that her luck is finally changing. However, appearances can be deceiving, and the handsome stranger is hiding a terrible secret. Megan quickly discovers the truth is far more disturbing than she ever imagined when she's trapped in a terrifying world from which she might never break free.
