Old Man's War Series
by John Scalzi
The premise is simple but grim: on your seventy-fifth birthday, you sign up for the Colonial Defense Force. You leave Earth behind for a body that is genetically engineered for war, green-skinned and enhanced, to fight alien species in a universe that is far more hostile than humanity ever imagined. John Scalzi nails the feeling of being a soldier who is simultaneously a veteran of life and a novice at space combat. The pacing is breathless, moving from boot camp to interstellar skirmishes without losing its sharp, conversational wit. It manages to be both a high-octane action romp and a sobering look at the moral cost of survival. This is for the reader who wants their military sci-fi with a heavy dose of humanity and enough humor to keep the dark reality of war from feeling completely hopeless.
