About The Expanse

Two hundred years from now, humanity has spread across the solar system — Earth, a crowded and politically fractious Mars, and the asteroid Belt, whose miners and dockworkers live under the thumb of both. When a conspiracy on an ice hauler triggers a chain of events involving a missing girl, a protomolecule that rewrites the rules of biology, and the fragile balance between three rival powers, a rag-tag salvage crew on the gunship Rocinante and a jaded Belter detective get pulled into events that will decide whether humanity survives contact with something that isn't from around here.

James S. A. Corey — the pen name of Daniel Abraham and Ty Franck — builds a nine-book saga that starts as hardboiled noir crossed with a submarine thriller in zero gravity and grows, book by book, into something closer to first-contact space opera, with newly opened alien gates leading to a wider, stranger galaxy. The physics are grounded (no artificial gravity without spin or thrust, no sound in vacuum, real orbital mechanics), the politics feel lived-in, and the large ensemble cast is tracked across decades. It's for readers who want epic-scale science fiction that never loses sight of the individual people caught in it, adapted into the acclaimed Expanse television series (2015-2022).

How to read this series

Read the nine novels in publication order, starting with Leviathan Wakes — this is one continuous story told across a widening cast and timeline, with no alternate chronology to consider. Each book picks up soon after the last, though the series does make occasional multi-year time jumps within the main sequence (most notably before Nemesis Games and again before Persepolis Rising).

Alongside the novels, the authors wrote a set of shorter novellas and short stories that fill in side characters and events between the main books (The Butcher of Anderson Station, Gods of Risk, The Churn, The Vital Abyss, Strange Dogs, Auberon and The Sins of Our Fathers); all are collected together in Memory's Legion. They add texture but aren't required to follow the main plot, so new readers can skip straight through the nine novels and come back to Memory's Legion afterward.

Frequently asked questions

How many books are in The Expanse series?

There are 9 main novels, from Leviathan Wakes (2011) to Leviathan Falls (2021), plus a collection of novellas and short stories gathered in Memory's Legion (2022).

What order should I read The Expanse in?

Publication order, starting with Leviathan Wakes. The nine novels are one continuous, forward-moving story, so there's no separate chronological order to worry about.

Do I need to read the novellas?

No. The novellas and short stories collected in Memory's Legion add backstory and side-character depth but aren't required to follow the main plot of the nine novels. Read them alongside or after the main series, in whatever order you like.

Is The Expanse series finished?

Yes. Leviathan Falls (2021) is the intended ninth and final novel, and authors Daniel Abraham and Ty Franck have said the main story is complete. They've since moved on to a new, unrelated series, The Captive's War, beginning with The Mercy of Gods (2024).

Is The Expanse TV show the same as the books?

The Amazon/SyFy television series (2015-2022) closely follows the novels for its first several seasons before diverging and ending earlier than the books do, wrapping up around the events of book six, Babylon's Ashes.
