Heaven’s River: Bobiverse, Book 4 by Dennis E. Taylor

Synopsis:
“Civil war looms in the Bobiverse in this brand-new, epic-length adventure by Audible #1 bestseller Dennis E. Taylor.
More than a hundred years ago, Bender set out for the stars and was never heard from again. There has been no trace of him despite numerous searches by his clone-mates. Now Bob is determined to organize an expedition to learn Bender’s fate — whatever the cost.
But nothing is ever simple in the Bobiverse. Bob’s descendants are out to the 24th generation now, and replicative drift has produced individuals who can barely be considered Bobs anymore. Some of them oppose Bob’s plan; others have plans of their own. The out-of-control moots are the least of the Bobiverse’s problems.
Undaunted, Bob and his allies follow Bender’s trail. But what they discover out in deep space is so unexpected and so complex that it could either save the universe — or pose an existential threat the likes of which the Bobiverse has ever faced.” -Audible

Opening thoughts:
I’m pretty excited to read this book because I loved the first three parts of this series. I’m excited to see where the story goes in this last installment. I thought that the third book seemed like a proper ending to a trilogy, so I’m curious what this one will be about.

Closing thoughts:
This was a great ending to the series! It definitely felt like an extra adventure to the main plot that happened from books 1-3, but it was enjoyable nonetheless.
I do love how it closed the loop on Bender’s unsolved mystery. And it was great how they brought Bob back into the fold as the main protagonist.
The other idea I really liked was how they explored “replicative drift” as well as the idea of “souls.” It was something I wondered about, but I’m glad that they tied up that loose end.
It would be cool if they eventually turned these books into movies. It’s such an epic, sci-fi story. Not sure if it would translate well into the big screen, or even into a series, but I’d definitely be interested in it.
Overall, highly recommend if you like the series (obviously) and if you in general love a good sci-fi reading.
One Takeaway / Putting into practice:
Probably the biggest and most obvious takeaway for me would be:
- The *true* golden rule: treat others the way they want to be treated
This makes sense, especially the way Teresa explained it. It’s important to remember not to treat others the way you want to be treated, but rather the way they want to be treated.
Nutshell:
Book 4 in the Bobiverse series has original Bob in search of Bender who went missing years ago. Bob has to work with the rest of the Bobiverse to bring him home from a place called “Heaven’s River.”
