2016’s Dark Matter was excellent: yes, it was light & fun, a thriller, but it was also a truly clever story in a multiverse setting that didn’t short circuit logically. Blake Crouch tried to emulate that succesful formula again in his latest book, this time using time travel as a way to conjure up multiple versions of reality.
Just to get things out of the way: Recursion starts promising, and overall it’s a fast paced page turner, but halfway the book it becomes clear this really is pulp of the worst sort. Blake pulls the quantum card casually – using just a few sentences – trying to justify nonsense: generally a good tell to spot bluffing.
Sadly, it only gets worse after that, utterly failing at inner consistency – even though Blake flashes “Clifford Johnson, Ph.D., professor in the Physics and Astronomy Department at the University of Southern California” in the acknowledgments. Clifford “provided valuable insight in the final stages of the manuscript.” Blake talked to some professor: the hallmark of serious science fiction! But obviously, “all mistakes, assumptions, and crazy theories are mine alone”. You see: even the acknowledgments are riddled with cliché. When Blake near the end of the novel suddenly jerks “micro black holes”, wormholes and muons out of his hat, it becomes clear Clifford didn’t save the novel from being preposterous.
