Black parachutes fall from the sky: young soldiers - and a dog - on a rescue mission in a remote part of Afghanistan.

But the mission ends in chaos, and Mark and Prince embark on a perilous journey through enemy territory. Will they make it back to base? All they have is each other. All they can do is survive, today, tomorrow and the next day.

A dramatic, powerful story of war and the bond between a young soldier and a dog, from the acclaimed author of Into That Forest.
