You're looking for your son. But she found him first. When a little boy goes missing, his mother desperately wants to find him… before someone else does. Libby would do anything for her three-year-old son Ethan. And after all they've been through, a holiday seems the perfect antidote for them both. Their hotel is peaceful, safe and friendly, yet Libby can't help feeling that someone is watching her. Watching Ethan. Because, for years, Libby has lived with a secret. Just days into their holiday, when Libby is starting to relax, Ethan steps into an elevator on his own, and the doors close before Libby can stop them. Moments later, Ethan is gone. Libby thought she had been through the worst, but her nightmare is only just beginning. And in a desperate hunt for her son, it becomes clear she's not the only one looking for him. Who will find him first?
