Dark Matter
Blake Crouch
My Review
I loved Blake Crouch's other book, Recursion. It was quite the mind warp, but in a fascinating way. Dark Matter started off strong. Then I began questioning the logic of what was happening. I had several conversations with Ethan about it. The fact that another universe was an exact copy of the existing universe, with just a few significant changes, how in the world could it have made it all the way to the one single point of divergence without being drastically different in every way?
But then, Crouch solved my dilemma by introducing an infinite number of universes, each of which could be entered and designed based on the main character's state of mind. Okay, that made more sense (as much as a sci-fi does, anyway).
But then there was more than one Jason, eventually over a hundred or more, all slight divergences of one world, coming together into the final world where each one thought they were the original Jason. This got weird and didn't do a great job of explaining how that even happened. Or maybe it's obvious and my pea-brain can't comprehend it. I don't know.
Still a fun book and an interesting way to look at our universe.
