The complicated nuances of teenage friendship are captured perfectly in this story of summer adventure and exploration by award-winning author Keith Gray.

Marshall feels the need to escape because things are so tough at home. Rory is just happy it’s the first day of the summer holidays. While out on their bikes they stumble across a long-forgotten underground bunker at the edge of the woods.   This is the den, and going down inside will stretch their friendship to its limits. There will be rivalry and betrayal, but can wrecked relationships be saved before the summer has even begun?
