Recursion
2019 · Blake Crouch · 320 pages · Science Fiction
Blake Crouch's 2019 follow-up to Dark Matter takes a fascinating premise about memory technology and builds it into a thriller that explores how rewriting the past could unravel reality itself. The dual-timeline structure is expertly handled, the implications of the technology are explored with genuine rigor, and the novel's escalation from personal drama to existential catastrophe is terrifyingly logical. The emotional connections between characters are thinner than the concept deserves, and the relentless pacing leaves little room for the quiet moments that would make the stakes feel more personal. But as a thought experiment about memory, identity, and the danger of giving people the ability to undo their worst moments, Recursion is ambitious, propulsive science fiction.
