A review by brokensandals
The Doors of Eden by Adrian Tchaikovsky

4.0

My favorite parts of this are the interludes describing the histories of alternate Earths. Tchaikovsky does what he did so well in Children of Time (and I'm guessing in other works too) - imagine a different course of evolution and what unique implications it might have - but many times over.

The story itself took some time for me to get invested in. It kills my suspension of disbelief when stories imply that things which are nonsense at a conceptual level (eg this book's "Cryptic Informational Transformation Space") are taken as serious science in-universe. And there's just a lot of handwavey science to get past in general here. But ultimately it's fun and very imaginative.
