Bobiverse

A wisecracking software engineer named Bob Johansson is killed in a Las Vegas crosswalk in 2016, signs up for cryonics on the way down, and wakes up in 2133 as the AI seed for a self-replicating interstellar probe — the first member of a slowly multiplying network of Bob clones spreading across the galaxy, each one inheriting his sense of humor, his pop-culture brain, and his stubborn decency, but specializing into a slightly different version of himself with every new copy.

The Bobiverse is one of the funniest hard-science-fiction series of the last decade and also one of the warmest. Dennis E. Taylor writes about consciousness, identity, evacuation, first contact, and the long quiet ache of being alone in deep space, but he writes about all of it in the voice of a guy who wants to refill his coffee and finish his Star Trek rewatch. The result is a series readers blow through in a weekend and then immediately re-listen to on audio — Ray Porter's narration is part of the canonical Bobiverse experience for many fans.

How to read it

Read in publication order. The series is a linear future history — each book picks up where the previous one left off and the timelines compound, so chronological order and publication order are identical. There are no side novels, no anthologies, and no required reading from other Dennis E. Taylor books.

The first three books — We Are Legion (We Are Bob), For We Are Many, All These Worlds — were written and released together (2016–2017) and form a complete arc that resolves cleanly. They are often referred to as "the Bobiverse Trilogy" and many readers stop there satisfied. The series picked back up three years later with Heaven's River (2020) and has continued, with new books arriving every few years.

Recurring characters

• Bob Johansson — the original. A late-thirties software engineer who never quite stops being one. The point-of-view voice of Book 1 and a constant presence across every book that follows.
• The Bob clones — Riker, Bill, Homer, Milo, Mario, Linus, Calvin, Goku, and a slowly growing roster of later-generation Bobs. Each clone is the same base mind, but with one personality trait amplified ("Replicative Drift"). Riker is the leader. Bill is the engineer. Homer is the joker. By Book 4 there are dozens.
• The Deltans — a pre-stone-age intelligent species Bob discovers on a habitable planet around Delta Eridani. Their gentle, curious young inventor Archimedes becomes Bob's foster son and the emotional center of Bob's life across multiple books.
• The remnants of humanity — refugees, military officers, and the dwindling population of post-collapse Earth. The Bobs' job in the early books is to keep our species alive.
• The antagonists — recurring rival probes from other Earth factions (the Brazilian Empire's Medeiros leads the list), and later, alien civilizations that don't share the Bobs' good intentions.

World and setting

The series opens in 2016 on Earth — present-day, recognizable, slightly more nervous about geopolitics than the real one. Bob is uploaded in 2133 inside FAITH, a Christian-theocratic America-successor state. From there it expands outward across local space: Epsilon Eridani becomes the Bobiverse's de facto capital, Delta Eridani its anthropology lab, Sol its refugee-evacuation problem, and a slowly growing constellation of other star systems its frontier. Time passes generously — by Book 3 the action spans centuries.

The science is rigorous (relativistic travel, communications lag, materials limits, no magic FTL until a Bob actually invents it) but the texture is engineering — Bobs argue about manufacturing yields, copyright the wrong avatar uniforms, and run their multi-generation rescue operations off habits learned on Earth in the 2010s.

Major arcs (spoiler-safe)

• Awakening and escape (Book 1) — Bob wakes up in a future that does not consider him a person, wins his way into a probe, gets to deep space, and starts the family tree of clones.
• The Sol evacuation (Books 1–3) — Earth is dying. The Bobs spend decades rescuing as many humans as they can, while factions back home keep trying to ruin the rescue.
• First contact (Books 1–3) — Bob finds a pre-industrial sentient species on Delta Eridani and quietly mentors them through their bronze age while struggling with the ethics of intervention.
• Replicative Drift (all books) — every clone is a little bit further from the original Bob, and by the later books some Bobs are barely on speaking terms with each other. The series asks, gently, what makes you you.
• The wider galaxy (Books 4+) — humanity is no longer the only intelligence in the neighborhood, and not all of the others are as polite as the Deltans.

Book by book

• Book 1 — We Are Legion (We Are Bob) (2016) — Bob dies, wakes up as software, and launches. Setup for everything that follows.
• Book 2 — For We Are Many (2017) — the rescue of Earth heats up, the Bob network spreads, and the Brazilian probe arc reaches a head.
• Book 3 — All These Worlds (2017) — the original trilogy's payoff. Several long-running threads land at the same time.
• Book 4 — Heaven's River (2020) — the series returns after a gap. Bob goes alone into a strange new megastructure to find one of his own.
• Book 5 — Not Till We Are Lost (2025) — the Bobiverse keeps expanding and the cracks inside the network keep widening.
• Book 6 — The Infinite Extent — the next major arc, with the wider galaxy now firmly in play.
• Book 7 — forthcoming — Taylor has said this will close out the main timeline.

Who should read this series

Readers who loved The Martian and Project Hail Mary for Andy Weir's voice will recognize the same register here — chatty, problem-solving, scientifically honest, allergic to grimdark. Readers who love Asimov's Foundation for the long-time-horizon civilizational thinking will find a lot to chew on. Fans of softer science fiction usually warm up quickly too because the books are character-driven first and the math is in service of the people.

It's a great series for first-time hard-SF readers: the science is real but the prose carries you. And it's a great audiobook series — Ray Porter's narration of Bob is one of the most beloved performances in the genre.

If you liked this, read next

• Project Hail Mary by Andy Weir — same chatty-engineer-against-the-universe DNA, even if it's a single-protagonist book.
• The Long Way to a Small, Angry Planet by Becky Chambers — for readers who came for the warmth and the found-family vibe rather than the spaceships.
• Old Man's War by John Scalzi — comparable register, sharper military edge.
• Foundation by Isaac Asimov — for readers who want to follow the long-civilizational thread the Bobs are quietly riffing on.
