"Inventive, funny and engrossing, this book lingers long after you close it"--Tade Thompson, Arthur C. Clarke Award-winning author of Rosewater
"Full of sparking, speculative invention . . . The Doors of Eden is a terrific timeslip / lost world romp in the grand tradition of Turtledove, Hoyle, even Conan Doyle. If you liked Primeval, read this book"--Stephen Baxter
"What a ride . . . talks like big-brained science fiction and runs like a fleet-footed political thriller"--John Scalzi
"With The Doors of Eden, Tchaikovsky has created a fantastic and highly imaginative new genre: evolution SF"--Peter F. Hamilton
"Tchaikovsky weaves a masterful tale about how each version of Earth diverged during the various Epochs of its billion-year history. A frozen world computer mind, peaceful brilliant Neanderthals, family-friendly weasels out of a steampunk nightmare, gargantuan spacefaring trilobites, and even feathered dinosaurs combine for a suspenseful joyride through the multiverse."--Booklist
"Tchaikovsky's world-building is some of the best in modern sci-fi and now he has made an enchanting multiverse of parallel Earths"--New Scientist
