Best Sci-Fi Book Series to Binge in 2026

The best sci-fi book series to binge in 2026 include The Expanse by James S.A. Corey, The Murderbot Diaries by Martha Wells, Red Rising by Pierce Brown, and the Bobiverse series by Dennis E. Taylor. Whether you want space opera, hard sci-fi, or LitRPG, each series here earns the full binge.

Every few months someone asks me what sci-fi series they should read next. Not a single novel. A series. Something they can disappear into for weeks, the kind where you finish one book at midnight and immediately buy the next.

Some of the series on this list I've binged cover to cover. I can tell you exactly where they hook you, where they slow down, and whether the ending sticks the landing. Others I haven't read yet, but they show up on every recommendation thread, every Goodreads list, and every "what should I read next" conversation for a reason.

I'm including both, and I'll be honest about which is which.

Series I've Binged

These are series I've actually read multiple books of. The recommendations come from genuine binge experience, not summaries.

1. The Murderbot Diaries by Martha Wells

Books: 8+ novellas and novels (ongoing) · Start with: All Systems Red

A security robot hacks its own governor module and just wants to watch soap operas in peace. That's the pitch, and it's perfect. The first four entries are novellas you can finish in a sitting each, which makes the series dangerously easy to binge.

You tell yourself "just one more, they're short" and suddenly it's 2 AM and you're halfway through Network Effect. That's the book where the stakes stop being episodic and the relationships start carrying real cost. Murderbot's internal monologue goes from funny to something that catches you off guard emotionally.

I wrote a Network Effect Is Where The Murderbot Diaries Starts Over, and I've got a complete The Murderbot Diaries Reading Order: Complete Guide (2026) including the novellas most people accidentally skip. The audiobook narration by Kevin R. Free carries Murderbot's dry, anxious personality in a way that makes the binge even faster.

2. Skyward by Brandon Sanderson

Books: 4 novels + 3 novellas (complete) · Start with: Skyward

Sanderson is known for fantasy, but Skyward is pure sci-fi with his signature worldbuilding depth. Spensa is a fighter pilot in a civilization trapped on a planet by an alien blockade. The first book reads like Top Gun meets a mystery about what humanity is really doing there.

I read all seven entries back to back. The novellas between the main novels shift perspectives to other characters and fill in pieces of the larger puzzle. Cytonic takes the series in a completely different direction, and Defiant closes the series out without fumbling the ending.

The whole thing is complete. No waiting years between releases. If you're a Sanderson reader who skipped this because "it's his YA series," you're missing his most tightly plotted work.

3. Bobiverse by Dennis E. Taylor

Books: 5 (ongoing) · Start with: We Are Legion (We Are Bob)

Bob Johansson dies, gets his brain uploaded into a Von Neumann probe, and spends the next several centuries replicating himself across the galaxy while trying to save what's left of humanity. The premise sounds like hard sci-fi, but the execution is closer to a conversation with your funniest engineer friend who happens to be exploring the cosmos.

By Heaven's River (Book 4), some of the Bob clones have drifted so far from the original that they barely count as Bob anymore, the philosophical questions about identity move to the foreground, and the alien civilizations feel like nothing from the human playbook. I reviewed Heaven's River when I finished it.

I got through Not Till We Are Lost (Book 5) in two sittings. The kind of series where you're laughing at pop culture references one chapter and thinking about the nature of consciousness the next. Every book gives you at least one concept that sticks in your head for days. If you want the full reading order, including where the upcoming sixth book The Infinite Extent fits, here's my complete Bobiverse books in order guide.

4. The Dispatcher by John Scalzi

Books: 3 · Start with: The Dispatcher

The shortest binge on this list. The first two are under 150 pages each, and the longest still clocks in under 250. In a world where murder victims spontaneously reappear alive in their homes, a professional "dispatcher" kills people for a living as a public service.

A murder mystery where nobody stays dead sounds like it shouldn't work. Scalzi makes the rules tight enough that real tension builds anyway. I listened to the first two on audiobook in a single weekend.

If someone tells me they want sci-fi but don't have time for a 12-book commitment, this is what I hand them.

5. Dungeon Crawler Carl by Matt Dinniman

Books: 8 (ongoing) · Start with: Dungeon Crawler Carl (Book 1)

Earth gets consumed by an alien entertainment corporation. The survivors crawl through a massive dungeon while the rest of the universe watches like reality TV. Carl, a regular guy in his bathrobe, and Princess Donut, his ex-girlfriend's cat who got stat-boosted into a sentient diva, are the heart of the whole thing.

I finished Book 1 and went straight into Book 2. That doesn't happen for me unless a series has its hooks in deep. Dinniman uses LitRPG game mechanics to build tension, not to bore you with stat sheets, and the emotional beats sneak up on you between the jokes.

Eight books in and the community consensus is that it keeps getting better. I put together a list of 19 Books Like Dungeon Crawler Carl (After Book 8) if you want to explore the genre further.

The Consensus Picks

These are the series that show up on every "best sci-fi" list, every Reddit recommendation thread, and every Goodreads ranking. Some I've read the first book of, some are still on my shelf. I'll be upfront about where I stand with each.

6. The Expanse by James S.A. Corey

Books: 9 (complete) · Start with: Leviathan Wakes

Nine books, all finished, with a TV adaptation that ran six seasons. The Expanse is the modern benchmark for space opera. Humanity has colonized the solar system, tensions between Earth, Mars, and the Belt are boiling over, and a mysterious alien technology threatens to upend everything.

The series regularly appears alongside Dune at the top of Goodreads' sci-fi series rankings. Nine books means you can live in this universe for months. The TV show is worth watching alongside or after, but the books go further and end differently.

7. Red Rising by Pierce Brown

Books: 6 (ongoing) · Start with: Red Rising

A color-coded caste system on Mars, a protagonist who infiltrates the ruling class from the bottom, and a series that starts as a Hunger Games comparison and evolves into something far more ambitious. Red Rising has one of the most dedicated binge-reading communities online.

The first trilogy is a complete arc. The second trilogy (starting with Iron Gold) shifts to multiple POVs and a wider scope. Tim Gerard Reynolds voices Darrow across the saga in a performance frequently cited as one of the best in sci-fi audiobooks, with additional narrators joining for the second trilogy's POVs.

8. Dune by Frank Herbert

Books: 6 (original series) · Start with: Dune

Desert planet, political intrigue, prescient messiah, sandworms the size of buildings. The first book is a five-star experience that earned its reputation across six decades. The worldbuilding is so dense you catch new layers every time you revisit it.

I've read and reviewed the first book. It took me weeks to properly sit with, and the fact that five more Herbert originals exist makes this the deepest rabbit hole on the list. The Villeneuve films are excellent entry points if you want to see the world before committing to the prose.

9. Children of Time by Adrian Tchaikovsky

Books: 4 (ongoing) · Start with: Children of Time

Spiders. That's the hook. A terraforming experiment goes wrong, the intended primates never make it, and an accelerated evolution virus lands on arachnids instead. You're rooting for them by chapter three.

I read the first book and it earned every bit of its reputation. The perspective shifts between the human crew and the evolving spider civilization are unlike anything else I've encountered in the genre. Children of Time won the Arthur C. Clarke Award, and the series is frequently cited alongside Murderbot and The Expanse as the best sci-fi of the 2010s and 2020s.

10. Hyperion Cantos by Dan Simmons

Books: 4 · Start with: Hyperion

Seven pilgrims travel to the planet Hyperion to face the Shrike, a creature that impales people on a tree of thorns extending through time. Each pilgrim tells their story on the journey, Canterbury Tales-style. The first book is regularly called the best sci-fi novel ever written on Reddit.

This is less of a "can't stop turning pages" binge and more of a "can't stop thinking about it" binge. The ideas stick with you for years. If you want sci-fi that reads like literature, start here.

11. Wool / Silo by Hugh Howey

Books: 3 (complete) · Start with: Wool

Thousands of people live in a massive underground silo. Going outside is a death sentence. Questioning why you're there is worse.

The mystery of what happened to the surface drives the entire trilogy. Howey parcels out answers at exactly the right pace, and each reveal reframes everything you thought you knew about the silo's rules. The books go deeper than the Apple TV+ adaptation (with its third season premiering July 2026), and the trilogy is complete.

12. The Three-Body Problem by Liu Cixin

Books: 3 (complete trilogy) · Start with: The Three-Body Problem

Hard sci-fi at a scale that makes most space operas look like they're set in a parking lot. The Dark Forest theory, the sophon surveillance, the dimensional attacks. Nothing else in the genre trades in ideas at this scale.

I gave the first book 3.4 stars. The Cultural Revolution opening is fascinating and the VR game sequences are bizarre in the best way, but the pacing asks for patience.

I respect it more than I loved it. If hard sci-fi that prioritizes ideas over characters is your thing, this trilogy will rewire how you think about the Fermi paradox. The Netflix adaptation is a decent entry point if you want a taste before committing to the prose.

Where to Start

Fastest hook: Dungeon Crawler Carl. Book 1 will tell you within 50 pages whether this series owns you.

Safest bet: The Murderbot Diaries. Short novellas, universally loved protagonist. You can bail after All Systems Red if it's not clicking. It will be clicking.

Deepest commitment: The Expanse. Nine books, a complete story, and a universe you can live in for months.

Most original: Children of Time. Evolving spider civilizations. Nothing else reads like this.

Pick one. Start tonight.
