Plot
Introduction
Old Man's War is about a soldier named John Perry and his exploits in the Colonial Defense Forces (CDF). The first-person narrative follows Perry's military career from CDF recruit to the rank of captain. It is set in a universe heavily populated with life forms, in which the spacegoing species compete for the scarce planets that are suitable for sustaining life. As a result, Perry must learn to fight a wide variety of aliens. The characters in Old Man's War have enhanced DNA and nanotechnology, giving them advantages in strength, speed, endurance, and situational awareness.
Synopsis
John Perry, a 75-year-old retired advertising writer, joins the Colonial Defense Forces who protect human interplanetary colonists. Volunteers sign letters of intent and provide DNA samples at age 65, which John and his now deceased wife Kathy had done ten years prior to the beginning of the story. After visiting his wife's grave to say goodbye (as volunteers can never return to Earth), Perry takes a space elevator to the CDF ship Henry Hudson, where he meets Thomas, Jessie, Harry, Alan, Susan and Maggie, fellow retiree volunteers. They dub themselves the "Old Farts".
Following a series of sometimes unusual psychological and physical tests, Perry's mind is transferred to a new body based on his genetic material. His new body is a younger version of himself, but genetically engineered with enhanced musculature, green skin, and yellow cat-like eyes. He now possesses enormous strength and dexterity, nanobot-enhanced artificial blood, enhanced eyesight and other senses, and most critically, a BrainPal—a neural interface that, among other capabilities, allows Perry to communicate with other members of the CDF via thought.
After a week of frivolity and libertinism in their new bodies, Perry and the other recruits land on Beta Pyxis III for basic training, during which the CDF's heritage in the United States armed forces is made clear when the recruits are taught the Rifleman's Creed. Perry's drill instructor, Master Sergeant Ruiz, adopts a tough and disdainful persona towards recruits, but discovers Perry is the creator of an advertising slogan Ruiz adopted as a personal mantra ("Sometimes you just gotta hit the road"). As a dubious gesture of respect, Perry is given the job of platoon leader during the weeks of training before he is shipped out to the CDF ship Modesto. His first engagement is with the Consu, a fierce, incredibly intelligent and religiously zealous alien species. Perry improvises a tactic which enables the CDF to win this first battle. This is soon followed by a number of battles with, among others, the bear-like Whaidians and the tiny Covandu. By the end of this last engagement Perry begins to suffer psychological distress over killing the Liliputian Covandu and accepts that he has transformed both physically and mentally.
Now a veteran, Perry participates in the Battle for Coral. The planet contains coral reefs valuable to the attacking Rraey, as well as a human colony (the Rraey also have a taste for human flesh). The CDF plans to rapidly counterattack with a small force before the Rraey establish their coral strip mining operations, but the Rraey are somehow able to predict the appearance of a space ship's skip drive (a feat that should not be possible) and use this knowledge to ambush and destroy CDF ships as they arrive in the Coral system. Perry's quick thinking allows him and his fellow soldiers on a transport shuttle to escape the wreckage of the Modesto and make for the planet's surface, but they are shot down. Everyone but Perry is killed in the crash; Perry is grievously wounded. Perry is left for dead by a Rraey search party (who find CDF soldiers inedible), and he is rescued by members of the mysterious "Ghost Brigades", the Special Forces units of the CDF. Perry thinks he has died when he sees a younger green version of his dead wife Kathy, who in reality is Jane Sagan, the leader of the Ghost Brigades rescue team.
