Brian Castner, the leader of a military bomb disposal team, recounts his deployment to Iraq with unflinching candor, and in the process exposes crucial truths not only about this particular conflict, but also about war throughout history. Castner's memoir brings to mind Erich Maria Remarque's masterpiece, All Quiet on the Western Front.

The thing that is most beautiful about Antarctica for me is the light. It's like no other light on Earth, because the air is so free of impurities. You get drugged by it, like when you listen to one of your favorite songs. The light there is a mood-enhancing substance.
