The Expanse Franchise Tracker covers the full Expanse universe on screen and in print — from James S.A. Corey's debut novel Leviathan Wakes (2011) through the sixth and final season of the Amazon Prime Video series (2022). That means 86 entries: 68 television episodes, 9 novels, 8 novellas and short fiction pieces, and 1 additional story.
The Expanse stands apart from most science fiction adaptations because the TV series and the book series are genuinely complementary rather than competing versions of the same story. The novels go further — covering material that the show, cancelled after Season 3 on Syfy and renewed by Amazon through Season 6, doesn't reach. Readers and viewers consistently recommend experiencing both tracks.
Expanse Watch Order: TV Series and Books
The tracker organises The Expanse into the TV series and the novel/novella sequence. Both follow the same main characters and story but diverge in scope from roughly Season 4 onward.
- TV-first viewers: All 6 seasons are available on Amazon Prime Video. The first three seasons adapt the first three novels closely. Seasons 4–6 cover books 4, 5, and 6 — but the TV series compresses and rearranges material, particularly in Seasons 5 and 6.
- Book-first viewers: The novels (9 books) run through events covered by the first 6 TV seasons and then continue into 3 additional books covering a 30-year jump forward that the show never reached.
- Novellas: The Expanse novellas (starting with The Butcher of Anderson Station) fill backstory gaps. They're short — most under 100 pages — and can be read alongside the relevant TV season or novel. The tracker maps each novella to its narrative position.
- Read the final 3 novels: Books 7–9 (Persepolis Rising, Tiamat's Wrath, Leviathan Falls) tell the end of the story the TV series never reached. Most fans who loved the show consider reading the complete novel series essential.
Frequently Asked Questions
- Do I need to read the books to understand The Expanse TV show?
- No. The TV series is self-contained through Season 6. The books provide significantly more depth on characters and worldbuilding, but the show works on its own. Most viewers watch first, then read the novels — particularly to experience the story's ending that the show didn't adapt.
- Why did The Expanse get cancelled by Syfy?
- Syfy cancelled The Expanse after Season 3 in 2018, reportedly due to licensing and streaming rights issues rather than ratings. A fan campaign — including a plane flying a banner over Amazon's offices — helped secure a renewal. Amazon Prime Video picked it up for Seasons 4–6.
- How many books are in The Expanse series?
- The main Expanse novel series comprises 9 books by James S.A. Corey (the pen name of authors Daniel Abraham and Ty Franck). There are also 8+ novellas and short stories that expand on character backstory and fill gaps between the novels.
- Does The Expanse TV show cover the whole story?
- No. The TV series covers approximately the first 6 novels. Books 7–9 (Persepolis Rising through Leviathan Falls) tell the conclusion of the story — a 30-year time jump that the show never adapted. Fans who want the full story should read the final trilogy.
- Is The Expanse hard science fiction?
- Yes, more so than most TV sci-fi. The Expanse is known for its physical realism — no artificial gravity unless ships are accelerating, realistic communication delays across planetary distances, and consequences for the human body in space. The series consulted scientists during production.
