The Doors of Eden by Adrian Tchaikovsky
5.0

Adrian Tchaikovsky is an author whose work consistently surprises and engages me. I knew I’d like this story when I saw a timeline of the history of this planet, shown by age (e.g., Ordovician, Permian, etc) before the story even started. And the story was wonderfully complex, fast-moving, with compelling situations and characters, with my favourite being Kay Amal Khan, profane, funny, and a massive genius of really esoteric and difficult mathematics, and Alison Mitchell, MI5 analyst and professional worry wort, whose analyses, guesses and hunches tend to be often better than anyone else’s, being a close second.
There are others we follow also as the story has disappearances, kidnappings, an evil rich dude manipulating things in the background, a multitude of strange creatures, and loads more great detail in a long but really interesting story of the ancient past, evolution, multiverses, and possibility.
