Dark Matter by Blake Crouch

Dark MatterDark Matter by Blake Crouch
My rating: 3 of 5 stars

The plot of Dark Matter explores familiar territory for any Sci-fi fan: the doppelganger or evil twin trope. The idea of two identical or nearly identical appearing people co-inhabiting the same world and interfering with the life of the other by impersonating them or unintentionally being mistaken for them goes back centuries. Twelth Night by Shakespeare is the earliest one I remember. I did a search online and immediately got a website that lists the 30 best films with twins or doppelgangers. That means there are even more than 30, although not all are science fiction. I can think of Twilight Zone and Star Trek episodes that did it too, not to mention many sci-fi books. So Crouch gets zero points for originality.

The beginning is well-written and exciting as Jason is attacked and kidnapped, not understanding what is going on. [mild spoiler warning – but this is early stuff you’ll learn soon if you read it]. He wakes up in a strange lab where everyone knows him, but he knows none of them. He’s a physicist who in this new world has supposedly won a prestigious prize, but he knows that instead he is merely a physics professor at a mediocre Midwest college. Crouch then leads us to understand that Jason has been subjected to quantum superposition, in effect inhabiting another world, one of the infinite number of possible worlds that exist simultaneously. It seems he, or the alternate version of him, invented a machine that can put objects or people in such a multiverse state. The rest of the book involves Jason trying to figure out what happened to him, why, and how to get back to his old life. The book became more tedious and implausible as it went on. I listened to the audiobook, which had a good reader, but all in all I found it unsatisfying. As I said at first – it’s well-explored territory and there are no new ideas here. Recursion, a later work by this author, has a very similar plot, only in that one, it’s time travel, not quantum superposition. This one is somewhat better written than that one, but that’s the best I can say for it.
