Driving home one night, stuck behind a rusty old car, Gabe sees a little girl's face appear in the rear window. She mouths one word: "Daddy." It's his five-year-old daughter, Izzy.

He never sees her again.

Three years later, Gabe spends his days and nights travelling up and down the motorway, searching for the car that took his daughter, refusing to give up hope, even though most people believe that Izzy is dead.

Fran and her daughter, Alice, also put in a lot of miles on the motorway. Not searching. But running. Trying to keep one step ahead of the people who want to hurt them. Because Fran knows the truth. She knows what really happened to Gabe's daughter.

Then, the car that Gabe saw driving away that night is found, in a lake, with a body inside and Gabe is forced to confront events, not just from the night his daughter disappeared, but from far deeper in his past.

His search leads him to a group called The Other People.

If you have lost a loved one, The Other People want to help. Because they know what loss is like. They know what pain is like. They know what death is like.

There's just one problem . . . they want other people to know it too.
