I've returned to the Bobiverse series more than once. It's definitely hard sci-fi, not something that the average reader who's not into sci-fi is going to love. But I really enjoyed getting to know the different Bobs and the clever ways the story morphed using long stretches of time, the von Neumann probe concept, etc. This is a re-reader for me!Only thing I'll note is that it can get a little political for me in a direction I generally avoid. :) Not the end of the world, but some of the main antagonists who keep coming back up are hyper-religious, clearly "conservative" folks. Not so compared to modern politics that I'm going to put it down, but if you're annoyed by that kind of thing, maybe steer clear.
