A snatched child, a cryptic message and a secret that will tear two lives apart.

Twenty years ago, one-year-old Lauren disappeared.

Now, ex-policeman Tom Lomax gets a mysterious offer from an heiress, Sara. She wants him to fly to her private island, all expenses paid. He cannot help but be intrigued. But Sara has received a troubling message and, despite all the privileges in her life, she now has no one to turn to and doesn't know whom she can trust.

In a matter of hours, both will be thrown headfirst into a race against time that will challenge everything they've believed in and change both their lives for ever.
