Ten years ago, seven kids were taken and held captive until their kidnapper took his own life. Now the seven are thrust back together on a trip in the mountains, cut off from civilization and hunted by an unknown assailant who wants them dead. From the author of The Assassin Game and Have You Seen My Sister comes another chilling thriller.

Years ago, a tragedy shook a small community in rural Scotland. A bus driver kidnapped seven elementary school children, drove them into the wildnerness, and held them captive in a cave, before jumping from a cliff's edge. The children were unharmed, and for the most part, young enough to grow up and put their ordeal behind them.

But on the anniversary of their childhood trauma, Maggie, Ant, Ben, Stephanie, Lawrie, Seb, and Cass are on a school survival trip up in the mountains and cut off from the rest of the world when a storm hits. There's no help in sight and the group discovers they are just a stone's throw from the scene of their traumatic kidnapping.

As the group struggles to survive the elements, they realize someone else is on the mountain, someone who knows what really happened all those years ago, someone who wants them dead and is willing to take them out one by one.
