What if Mars and Venus really were habitable and inhabited, as in many SF stories from the early sixties and before? In this alternate history series Mars and Venus were terraformed a long time ago and "seeded" with Earth life, including several different human species. On Earth everything is the same until the start of space exploration, but then the Cold War dampens down into a real, collaborative space race which overtakes the military budgets of both superpowers.
The vast investment in interplanetary exploration has changed this alternate history deeply, in ways mentioned in passing, including the close alliance of the United States, Great Britain and the Dominions; but there are other changes: In the Suez Crisis, Britain and France receive American support and succeed, and there is no Sino-Soviet split in 1959. The Soviet Union does not collapse, and there are two competing space efforts: the Sino-Soviet alliance and the US-Commonwealth alliance. The European Union is led by France, since the United Kingdom did not join it, but their space effort is considerably behind the others. The Sky People is set on Venus, while its sequel In the Courts of the Crimson Kings is set on Mars.
The Change is the overall name of the stories of the Nantucket series and the Emberverse series.
In Island in the Sea of Time the island of Nantucket is transported by an unknown phenomenon (called "The Event" in the series) back in time into the Bronze Age circa 1250s BC (corresponding to the late Heroic Age of Greek mythology). The trilogy describes the conflict between the different factions of the island's population—some trying to dominate the world for their own benefit, others trying to better it, while most just want to survive, work hard, and claw their way back to something approaching their pre-Event way of life.
The series consists of three books:
Additionally, the short story "Riding Shotgun to Armageddon" (1998) and the novelette "Blood Wolf" (2004) are also set in this series.
Dies the Fire (2004) shows the effects on the planet—a world Nantucket left—of something called "The Change". Electricity, guns, explosives, internal combustion engines, and steam power no longer work. The series mostly deals with the Willamette Valley area of Oregon, with some description of the United Kingdom. After describing how people in those places survive the loss of 600 years of technological progress, the primary focus of this series turns to a conflict between a Portland-based neo-feudal dictatorship created by a sociopathic history professor, and the free communities of the Willamette Valley, most notably the Wiccan Clan Mackenzie and a group led by a former Marine, the Bearkillers.
A second series, set 22 years after the Change, and now concluded, focuses primarily on the conflict between the Willamette communities, now united, and the evil Church Universal and Triumphant (the CUT):
A third series, set a generation later chronicles the adventures of Órlaith Mackenzie, the daughter of the High King and an attack from a reborn Empire of Korea in the Californian colonies of Montival. The series was intended as a trilogy, but has now expanded into a tetralogy and will chronicle Orlaith's adventures to find the Grass Cutting Sword before the forces of Montival go overseas to battle the evil of the Empire of Korea.
The conclusion of The Sword of the Lady offers a sort of explanation for the Change, which includes what appear to be Swindapa and Marian Alston, major characters from the Nantucket trilogy.
Further, the short stories "A Murder in Eddsford" (2008) and "Something for Yew" (2007) are also set in this universe, taking place in post-change Britain. The short story "Ancient Ways" (2010) takes place in Central Asia 57 years after the Change.
Additionally in 2015 an anthology series called The Change was released containing stories by numerous authors set in the world of the Emberverse.
The Urban Fantasy series features "Shadowspawn", an ancient subspecies of Homo sapiens (Homo sapiens nocturnis) who formed the basis of legends about vampires and werewolves and have been secretly controlling the world for most of human history.
These are a collection of post-holocaust fantasy novels, in which civilization was destroyed (probably by a nuclear war) in something near our present time and new civilizations have grown to take their place. The novels are set in about the year AD 5000. There are elements of magic or psionics present, but they are fairly low powered, while technology is approximately at the level of the historical Middle Ages. Two additional novels in this series (Lion's Heart and Lion's Soul, both by Karen Wehrstein) overlap these novels but were not authored or co-authored by Stirling. Shadow's Daughter by Shirley Meier is also part of the series. Snowbrother is also Stirling's first published novel. Saber and Shadow is a revised edition of The Sharpest Edge with a few new pages of story at the beginning and tweaks to the rest of the story to assure continuity with that new beginning. The end of the story remains the same. It also adds an appendix with explanation of the cultures and languages in the 5th Millennium, and a description of how the authors got together to write this series.
The Draka novels postulate a dystopian slave-holding militaristic African empire founded by British Loyalists who escaped to South Africa after the American Revolution rather than to Canada (as in our history). They were later joined by French Royalist émigrés, Icelandic refugees, and demobbed veterans of the Napoleonic Wars, then by tens of thousands of defeated Confederates after the American Civil War. Stirling provides a timeline for its historical development through the 19th and 20th centuries, first as the Crown Colony of Drakia (for Francis Drake), gradually breaking away from British control to become the Dominion, then the Domination, of the Draka. The Draka culture is remarkable for combining a strictly race- and class-based hierarchical society with near-complete gender-equality (including female soldiers in integrated military units in combat roles). The Draka are greatly outnumbered by their slaves, and quite ruthless in maintaining their rule. Compared to current western society, nudity and sexuality are much less taboo among Draka.
As a result of the intense manpower pressures stemming from their conquest of Africa through the 19th century, all Draka are liable for service in the military/security forces, and the Draka-only Citizen Force is by far the deadliest and most advanced military machine on the planet. But there are never enough Draka (only 30 million or so at the start of World War II) to go around, and the bulk of the Domination's Armed Forces are made up of "Janissary" Legions recruited from the Serf population. The Citizen Force provides the élite cutting edge, while the "Janissaries" are the cannon fodder.
Stirling frequently uses the Draka and other villains as point-of-view characters, leading to complaints that he has some sympathy with them. He is known to be dismayed by this analysis of his work. He describes the Draka series as dystopias based on "suppos[ing that] everything had turned out as badly as possible, these last few centuries". Stirling responded to these accusations in his novel Conquistador, which contained the quotation (variously attributed to Larry Niven or Robert A. Heinlein) "There is a technical term for someone who confuses the opinions of a character in a book with those of the author. That term is idiot."
The central theme of this series is the attempt to reunite a fragmented empire by an ancient and hidden colony-world military computer that survived the collapse of space travel and general loss of technology in society. The computer imposes a mission on a strong military leader, Raj Whitehall, to reunite the various nations of the colony in a series of military campaigns that from a technology perspective are roughly analogous to late 19th-century Earth-based warfare although the role of horses has been replaced with giant dogs. A mix of historical military and science fiction, the first five books follow the attempt to re-unify the colony world; the subsequent volumes address other worlds in future times and involve other central characters. The first five novels are currently available in omnibus editions The Warlord (two novels) and The Conqueror (three novels; both collections in 2005).

The first two volumes in this series, Falkenberg's Legion and Prince of Mercenaries, were solely the work of Jerry Pournelle. In 2002, all four Falkenberg books, including the two listed below, were published in a single volume, The Prince. The Falkenberg books are part of the larger "CoDominium" series, which also includes The Mote in God's Eye and The Gripping Hand by Pournelle and Larry Niven. Stirling's books in this series are popular with many Western soldiers for their portrayal of the mechanics of an ideologically driven insurgency.
