It's NYPD's Detective Josie King's last day on the force. As farewell toasts are raised, she receives a text-message that stops her breathing. Olive, her one-year-old goddaughter has been kidnapped! Now no longer a cop, and without the department's weight and resources behind her, she doggedly follows the clues the kidnapper sends her, determined to bring little Olive home. She knows this is personal. Someone is messing with her head, but who, and why? With the clock counting down and the hours shrinking, Josie finds Olive isn't the only person close to her being targeted by a monster from her past.
