Eleven novels for readers who loved James S. A. Corey's grounded physics, solar-system politics and slow-burn alien mystery, with how each one differs.
Short answer: finish the nine Expanse novels first. Then read Red Mars for the politics of a Mars colony, Saturn Run and Delta-v for realistic missions, and Revelation Space or Pandora's Star for a bigger alien mystery.
The Expanse begins with Leviathan Wakes (2011): Earth, an independent Mars and the Belt are in a cold war when a missing-person case and a destroyed ice hauler uncover something far bigger. Readers usually want three things from the next book: physics that matters to the plot, factions with real interests, and a mystery that grows. Each pick below says which of those it delivers.
| Book | Author · year | How it differs from The Expanse |
|---|---|---|
| The rest of The Expanse | James S. A. Corey · 2012–2021 | Same universe; read in order. |
| Red Mars | Kim Stanley Robinson · 1992 | Slower and more political; decades, not weeks. |
| Saturn Run | John Sandford and Ctein · 2015 | A single race to one target, not a whole system at war. |
| Delta-v | Daniel Suarez · 2019 | Near future; no alien mystery. |
| Seveneves | Neal Stephenson · 2015 | Orbital survival rather than settled planets. |
| Children of Time | Adrian Tchaikovsky · 2015 | Evolution and first contact rather than politics. |
| The Mote in God's Eye | Larry Niven and Jerry Pournelle · 1974 | Interstellar empire, not a solar system. |
| Revelation Space | Alastair Reynolds · 2000 | Grimmer and denser; much longer timescales. |
| Pandora's Star | Peter F. Hamilton · 2004 | Far-future scale with faster-than-light travel. |
| The Martian | Andy Weir · 2011 | One man, one planet, no politics. |
| SOLEN: The Eden Archive | Warren Pulley · 2026 · our series | The Martian side of The Expanse's world: a colony being built, not a navy at war. |
Leviathan Wakes is book one of nine; the series closes with Leviathan Falls (2021), and novellas fill the gaps between books. If you have only watched the TV adaptation, the books go well past where it ends.
How it differs: Same universe; read in order.
The founding of a Mars colony by the First Hundred, and the fight with Earth's governments and corporations that follows. The deep background for The Expanse's independent Mars.
How it differs: Slower and more political; decades, not weeks.
When an alien craft is spotted slowing near Saturn, the United States and China race crews across the solar system to reach it first. Ship engineering and great-power politics in Expanse style.
How it differs: A single race to one target, not a whole system at war.
A cave diver is recruited for a privately funded asteroid-mining mission. Close attention to orbital mechanics, life support and the economics of mining in space.
How it differs: Near future; no alien mystery.
When the Moon breaks apart, humanity has two years to get people into orbit. Dense with orbital engineering, then a jump of five thousand years.
How it differs: Orbital survival rather than settled planets.
The last humans, aboard an ark ship, reach a terraformed world where an uplifted species of spider has built its own civilisation. Winner of the 2016 Arthur C. Clarke Award.
How it differs: Evolution and first contact rather than politics.
An interstellar navy makes first contact with an alien species whose biology hides a dangerous secret. A classic of the slow-reveal alien mystery The Expanse also uses.
How it differs: Interstellar empire, not a solar system.
An archaeologist digs into the extinction of an alien race while a lighthugger crew comes looking for him. Dark, slower-than-light space opera with an ancient-technology mystery.
How it differs: Grimmer and denser; much longer timescales.
A wormhole-linked human Commonwealth investigates two stars that vanish behind a barrier. A huge ensemble cast, like The Expanse at its widest.
How it differs: Far-future scale with faster-than-light travel.
An astronaut stranded on Mars survives with engineering and stubbornness. For readers who liked how The Expanse treats physics as a plot problem.
How it differs: One man, one planet, no politics.
A hard science fiction Mars saga that follows one colony at Hellas Planitia across a century. In NovaSeed: Eden Rising, Carter and Alina find life in a subsurface brine pocket. Later books follow the colony as it grows and, in The Red Dominion, decides what kind of civilisation it is. The mission AI SOLEN keeps the record.
How it differs: The Martian side of The Expanse's world: a colony being built, not a navy at war.
Disclosure: NovaSeed Books publishes the SOLEN series, so it is included and marked as ours. All other picks are independent recommendations; we have no affiliate links.
A hard science fiction Mars colony saga across a hundred years, narrated in part by a mission AI. Available on Amazon in Kindle and paperback.
