Joe Haldeman's The Forever War (1974) follows a soldier conscripted into a centuries-long interstellar war against the alien Taurans, using relativistic space travel so that months spent in transit correspond to years or decades passing back on Earth. Haldeman later returned to the same conflict in Forever Peace (1997), a thematically connected but separate story, and Forever Free (1999), a direct sequel set years after the original war's end. The first novel won the Hugo, Nebula, and Locus awards and is considered a foundational work of military science fiction.

Orson Scott Card's Ender's Game (1985, expanded from his 1977 novella) follows child prodigy Andrew "Ender" Wiggin as he is recruited into a military training program built to prepare Earth's defenses for an anticipated third war against an insectoid alien species known as the Formics. The saga continues years later through Speaker for the Dead and Xenocide, following an older Ender as he confronts the moral weight of his role in that earlier conflict, and concludes the core arc in Children of the Mind, with Ender in Exile filling in the years between the first two books. Set within the wider Ender's Game universe, the series shifts from military coming-of-age story to slower, more philosophical science fiction as it progresses.

Frank Herbert's Dune Chronicles opens with 1965's Dune, set on the desert planet Arrakis where House Atreides takes control of the only source of the vital spice melange and young Paul Atreides is pulled into a struggle over its politics and religion. Herbert carried the story forward across five further novels — Dune Messiah, Children of Dune, God Emperor of Dune, Heretics of Dune, and Chapterhouse: Dune — following Paul's line over the following millennia, before Brian Herbert and Kevin J. Anderson later extended the saga. Many other editions of these six novels are omnibus and box-set repackagings rather than separate stories.

Arrakis. Dune. The desert planet, where empire runs on a single substance: the spice melange, which folds space, prolongs life, and unlocks prescience, and which exists nowhere else in the known universe. Frank Herbert's saga is a meditation dressed as an adventure — feudal houses and a secret sisterhood, engineered messiahs and the patient ecology of a world without water, all turning on the terrible gravity of who commands the spice. It reads like scripture and schemes like a war room, ten thousand years hence, among people who have outlawed the thinking machine and made instruments of themselves instead. At its heart stand Herbert's original six — Dune, Dune Messiah, Children of Dune, God Emperor of Dune, Heretics of Dune, Chapterhouse: Dune — a single deepening arc across millennia, arguing the whole way between prophecy and free will. Around that spine his son Brian Herbert and Kevin J. Anderson have raised a vast prequel architecture: Prelude to Dune, tracing the great houses a generation before Paul; Legends of Dune, reaching back to the crusade that broke the machines; the Schools of Dune cycle on the founding of Bene Gesserit, Mentat, and Navigator; the Caladan Trilogy and Heroes of Dune filling years the originals left in shadow. Many hands, dozens of volumes, one desert. What sets Dune apart is its refusal of the simple: religion is manufactured, heroes are hazards, and the sand itself — worm, water, ecology — acts as a political power. Begin where the universe did, with Frank Herbert's Dune (1965), and read the original six in order; you need nothing else to feel the full weight. The prequels are a country to explore afterward, taken by era. Beginnings are delicate times.

Hammer's Slammers follows an armored mercenary tank regiment, originally raised by the government of Friesland to crush a colonial rebellion, that goes on to sell its services across a scattering of future worlds under the hard-nosed Colonel Alois Hammer. David Drake, drawing directly on his own Vietnam-era service with the 11th Armored Cavalry, writes the unit's campaigns with a deliberately unglamorous, close-to-the-ground feel, treating mercenary war as dirty business rather than adventure. The series runs across many novels and story collections rather than one continuous arc.

Halo's tie-in novels expand the video-game franchise's war between humanity and the alien Covenant, and later the ancient Forerunners, across dozens of books by a rotating slate of authors overseen by the franchise's owner (Bungie, then 343 Industries). Eric Nylund's The Fall of Reach, chronicling the Master Chief's childhood conscription into the Spartan program, launched the line alongside the first game in 2001, and it has since grown to cover side characters, prequels, and new eras of the setting. It's licensed franchise fiction rather than a single authored series.
