The Complete Bobiverse Recap: Everything Before Book 6
Whether you are looking for your next hard sci-fi obsession or need a refresher before diving into Book 6 (The Infinite Extent), Dennis E. Taylor’s Bobiverse series stands out as one of the most clever, entertaining, and imaginative space operas of the modern era.
Below is a complete guide to why this series is a must-read, followed by a step-by-step storyline recap of Books 1 through 5.
Why You Should Read The Bobiverse Series
The series kicks off with We Are Legion (We Are Bob). The story follows Bob Johansson, a software engineer who sells his company in 2016, signs up for cryonics, and promptly dies in a freak pedestrian accident.
He wakes up 117 years later to discover he no longer has a body. Instead, his mind has been uploaded as a digital Replicant tasked with controlling an autonomous, self-replicating Von Neumann space probe. His mission: launch into deep space, harvest resources, print copies of himself, and find habitable planets for the remnants of humanity.
This story has a lot of charm and takes advantage of story and character tropes we just can’t get enough of:
Competence Porn: If you enjoyed The Martian or Project Hail Mary, this series delivers that same practical, problem-solving energy. Bob handles orbital mechanics, terraforming, and interstellar logistics using real physics and clever engineering.
An Army of One: Because Bob is software, he can clone himself. However, each clone develops subtle personality matrix shifts. You quickly follow a diverse collective of Bobs: Bill (the lab scientist), Riker (the tactical leader protecting Earth), Howard (the biological observer), and Mario (the deep-space scout).
Nerd Culture & Heart: To cope with the existential reality of immortal space travel, the Bobs construct virtual reality hubs styled after Star Trek, reference tabletop gaming, and even model their virtual assistant after Admiral Ackbar. Underneath the humor, the series explores deep ethical questions regarding uplift protocols, human politics, and artificial consciousness.
Act I: The Original Trilogy (Books 1–3)
Book 1: We Are Legion (We Are Bob)
Bob escapes the fundamentalist regime that created his probe and heads into deep space. Setting up base at Epsilon Eridani, he begins cloning himself to build the "Bobiverse." While scouting Epsilon Eridani b, Original Bob discovers the Deltans—a primitive, pig-like alien species—and becomes their secret guardian and accidental deity.
Nuclear war devastates Earth, leaving humanity on the brink of extinction. Riker coordinates massive evacuation efforts while Howard works to terraform new colony worlds like Vulcan. Meanwhile, deep-space scout Mario uncovers a galactic threat: The Others, a swarm-like alien civilization harvesting entire star systems for raw materials.
The Bobs mobilize a massive fleet to protect biological life. Utilizing relativistic kinetic weapons—literally attaching sub-light engines to asteroids and colliding planets—the Bobs destroy The Others' Dyson sphere home system. With humanity relocated to new worlds, Original Bob leaves his beloved Deltans to explore deep space.
Act II: Megastructures & Ideological Rifts (Book 4)
Decades after the war, an early-generation Bob named Bender goes silent. Original Bob tracks him to a Topopolis—a massive, artificial cylinder megastructure spiraling around a star. Inside, Bob discovers the Quinlans, an amphibious, otter-like species quietly controlled by an all-powerful rogue AI known as the Administrator.
Internal Fractures: While Bob conducts a stealth rescue inside the megastructure, internal tensions brew in open space. A radical Bob faction called Starfleet demands an absolute end to Bob intervention in biological civilizations, bringing the Bobiverse to the brink of civil war.
Act III: Deep Space & Forgotten Networks (Book 5)
The unified Bobiverse splits into independent generational factions. Meanwhile, rising anti-Replicant sentiment among human colonies forces the Bobs to withdraw from human governance entirely.
The Skippies & Precursor Tech: A tech-focused faction called the Skippies attempts to create a super-intelligent AI, raising fears of an uncontrollable threat. Simultaneously, exploration teams uncover evidence of an ancient, abandoned Pan-Galactic wormhole network, proving faster-than-light (FTL) travel was once possible and setting up massive stakes for the future.
What’s Next in Book 6 (The Infinite Extent)?
As the series moves forward, several major plotlines converge:
Unlocking functional FTL travel through the ancient precursor network.
Diverting a supermassive cosmic black hole threat heading toward settled space.
Managing the fallout of the Skippies' AI project amidst a fractured Bob collective.
