Caged Birds

"Not all birds are born to fly. Some prefer the safety of their homes, instead. So why do we cage up the best ones; the ones born wild and free, the ones born to fly?"

Christopher has been a part of the war since 67. That's four years. He has grown used to dead bodies, killing; has no emotions left. So why now, after all that time, does he somehow get buried underground in the middle of so many tunnels?
When Christopher meets a soldier from the other side; too big a heart, too many emotions, and new to his army, they must help each other escape before it is too late.

But when your trapped underground with your enemy, much more can be uncovered than you would have thought...
