I originally reviewed book 1 (We Are Legion) in the Bobiverse series back in December of 2024, and highly recommended it for sci-fi fans, and especially fans of Star Trek.
I finally got around to reading the other four books in the series (so far), and have nothing but praise for the 
whole story. As the Bobs clone themselves and build new Von Neumann probes to explore the galaxy further and in greater detail, the names of the Bobs (a.k.a. Will, Hugh, Locutus, Gandalf, Icarus, and so on, all named for sci-fi, fantasy, or mythical characters) grow exponentially. It’s a little trouble, at first, keeping track of them all, but as the story builds, it gets easier. So much is happening in each of these books that it’s hard to put one down. I completed the last two, (Heaven’s River and Not Till We Are Lost), in less than a week.
While there is a lot of humor and geeky references that sci-fans will love, there are also healthy dollops of thought-provoking story twists, especially as the series gets deeper into the world of Bob. Factions develop 
in the cloned individuals, confirming the possibility of replicative drift, and some of the newer Bobs want very different things. Humanity is no longer the center of their universe, and they aren’t all that keen on continuing to get (or stay) involved with ephemerals—even those other sentient races they encounter. The difference between those Bobs, and the few who get so involved they can’t easily extricate themselves, is vast and creates problems for the whole. But it isn’t just the tension in the story that makes these issues relevant; they raise ethical quandaries that, in some cases, have no “right” answer. I found it interesting how the author explained each from the characters’ points of view.
There’s also a lot of hard sci-fi detail, so if you love that sort of thing, you’ll want to read these books. I didn’t 
always understand the science, but it wasn’t so thick that it affected my ability to follow the story. Overall, the Bobiverse volumes are easy reads, entertaining and fun, a nice escape from the real world. And Taylor does a great job of layering the plotlines for the different story arcs, so you’ll want to keep reading and see what happens next.
The sequels are, in order, For We Are Many (© 2017, ASIN: B01MZI77C0); All These Worlds (© 2017, ASIN: B0736185ZL); Heaven’s River (© 2020, ISBN 13: 978-1680682106), and Not Till We Are Lost (© 2025, ISBN 13: 978-1680683455). Book six is in the works, but there is as yet no estimated release date. I’ll definitely be watching for it. Most highly recommended for fans of sci-fi and geekdom.
