Books like The Expanse
If The Expanse left a hole in your shelf.
Astra Echoes is a character-driven science fiction series by Gaby Oron, often picked up by readers looking for books like The Expanse. It trades the solar system for the colony worlds of the Known Universe: six centuries of interstellar settlement, faction war, and ordinary people making impossible choices inside machinery far bigger than they are. The series starts with the novella The Quiet Divide — and you can read the first chapter free.
The parts that will feel like home.
People first, physics close behind. Like Holden’s crew, the people of Astra Echoes aren’t chosen ones. Dr. Cira Langley is a researcher and a mother on a station above a colony world when the night goes wrong — and everything that follows comes from her choices, not from destiny.
Faction politics with teeth. The Expanse ran on the triangle of Earth, Mars, and the Belt. Astra Echoes runs on a wider board — the Alliance of Free Worlds, the Praetorium, the Councils, the Void Handlers, the Black Division and more — each with reasons that make sense from where they’re standing. Nobody twirls a moustache; everybody has a constituency.
Consequences that stay broken. Stations tear apart, and the story is about what that costs — for the people who were standing on them, and for everyone who has to live in the aftermath.
A big object nobody fully understands. The Expanse had the protomolecule and the ring gates. Astra Echoes begins with the Astra Gate — discovered in 2024, it put colony ships into the dark, and humanity has been living with the consequences ever since.
The parts that are their own thing.
The timeline is the epic. The Expanse spans decades. Astra Echoes spans six centuries — you watch colonisation curdle into history, and history harden into the factions that go to war in the 2600s.
It starts with a mother. At the centre of the series opener is a woman, a newborn, and a discovery that makes both of them dangerous. If you wanted more of the quieter, human stakes alongside the battles, this is that thread given the wheel.
Novella-sized on-ramp. You don’t commit to a 500-page opener. The Quiet Divide and Ashfall Rising are novellas; the full trilogy begins fifteen years later with Echoes of Erigo. You’ll know within an evening whether this universe is for you.

A straight answer.
No indie series is The Expanse, and this page won’t pretend otherwise. What Astra Echoes shares with it is a conviction: that space opera works best when the politics are believable, the physics have weight, and the people caught in between are worth caring about. If that’s what you loved, start with the free chapter and judge for yourself.
Quick questions.
- Is Astra Echoes similar to The Expanse?
- Yes, in spirit: both are character-driven space operas built on faction politics and realistic consequences. Astra Echoes covers a longer timeline — six centuries of interstellar colonisation — and begins with novellas rather than a full-length novel.
- Where should I start with Astra Echoes?
- Start with The Quiet Divide, then Ashfall Rising. The trilogy begins fifteen years later with Echoes of Erigo.
- Do I need to have read The Expanse before reading Astra Echoes?
- No. Astra Echoes stands entirely on its own; the comparison is simply the fastest way to describe its character-driven, faction-politics style of space opera.
- Is there a free sample of Astra Echoes?
- Yes. Joining the Astra Echoes newsletter at astraechoes.co.uk/newsletter gets you the first chapter free, matched to where you are in the saga.
