#27, With the Old Breed: At Peleliu and Okinawa, by Eugene B. Sledge

This grim but fascinating memoir of a Marine in two of the toughest battles of the Pacific War gives a front-line soldier's view of the fear,tedium, and soul-killing horror of life on the front-lines. Honest and compassionate, it makes you pray for an end to war so no one has to endure anything like this again. If you have seen "The Pacific", you'll recognize many of the incidents.
