The Naked Edge (Unabridged‪)‬

Once they were boyhood best friends, playing in the woods near their homes, pretending to be soldiers surviving behind enemy lines. Grownup, they belonged to Delta Force and later worked as protectors for the world's best security company. Now their lives have taken drastically different paths, pitting them against one another, forcing them to play their boyhood game again, this time to learn who dies. The survival of a great city hangs in the balance as two friends-turned-enemies hunt one another and discover that there's a line between predators and prey, a line that's called The Naked Edge.
