John Perry joins the Colonial Defense Forces on his 75th birthday. Earth’s elderly can enlist in exchange for new, genetically enhanced bodies and a chance to fight for humanity’s place among hostile alien species. Perry’s wife is dead. He has nothing left to lose. The CDF transfers his consciousness into a young, green-skinned supersoldier body and sends him to war.
John Scalzi posted the first chapters on his blog in 2002. Tor Books picked it up, and Old Man’s War was published in 2005. It was nominated for the Hugo Award. Scalzi wrote in a direct, conversational style that felt closer to Heinlein than to the literary science fiction of the period. The book moved fast and didn’t waste time on exposition.
The sequels expand the universe. The Ghost Brigades follows the Special Forces, soldiers created from the DNA of the dead. The Last Colony puts Perry in charge of a new human settlement caught between political factions. Zoe’s Tale retells those events through his adopted daughter’s eyes, adding an entirely different layer to the same plot.
The Human Division and The End of All Things were originally published as serial novellas before being collected as novels. They deal with the breakdown of interstellar diplomacy and the threat of a conspiracy that could end human space colonization. Scalzi has not ruled out returning to the universe.
