Old Man’s War Summary
Spoiler Warning: This section recounts the complete plot, including the ending.
Humanity has colonized space under the Colonial Union. Earth remains isolated from advanced technology. On Earth, 75-year-olds can enlist in the Colonial Defense Forces. They are promised rejuvenation and a new life, but they must leave Earth forever.
John Perry enlists after his wife Kathy dies. He boards a space elevator and travels to a colonial station. Recruits are legally declared dead. Their earthly assets are distributed to heirs.
On the troopship *Henry Hudson*, Perry meets fellow recruits known as the Old Farts. The CDF does not repair old bodies. It transfers consciousness into new, genetically optimized ones.
These new bodies have green skin, cat-like eyes, and SmartBlood. An internal computer called a BrainPal connects soldiers to their equipment. Recruits get one week to adjust before training begins.
Basic training takes place on Beta Pyxis III. Master Sergeant Antonio Ruiz pushes the recruits through brutal exercises. Perry becomes a platoon leader. Training stresses that enhanced bodies are the minimum needed to survive alien threats.
Perry is assigned to the *CDFS Modesto*. He fights multiple alien species across different planets. Friends die in combat, accidents, and ambushes. Perry rises through the ranks as losses harden him.
The Battle for Coral changes everything. The Rraey, using technology that predicts human ship movements, ambush the fleet. The *Modesto* is destroyed. Perry crashes on the planet and survives alone.
A Ghost Brigades unit rescues him. During recovery, Perry notices a soldier who looks exactly like Kathy. Her name is Jane Sagan. She was created from Kathy’s DNA for Special Forces. Jane has no memories of being Kathy, but she wants to learn about her genetic source.
The Special Forces plan a counter-assault. They must capture the Rraey’s skip-prediction technology, which the Consu provided. Perry joins the mission as a lieutenant.
A diplomatic meeting with the Consu reveals they gave the technology to improve both races through more efficient war.
The final mission uses a high-orbit insertion. The soldiers fall to the planet as debris. They capture the tracking station. Perry saves Jane, who is badly wounded. He retrieves the data module containing the Consu technology manual.
The mission succeeds. Perry is promoted to captain. Jane is transferred elsewhere. Perry serves on the ship *Taos*.
The book ends with a BrainPal message from Jane.
She sends a picture of a sunrise. She tells Perry about a place where retired Special Forces learn to be human. She asks him to find her when his service ends.
