“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

“The Doors of Eden shows a combination of tight, evocative prose combined with erudition. In a story whose scope is the broad canvas of the history of all life in the universe, Tchaikovsky manages to zoom in on human moments without breaking a sweat. Inventive, funny and engrossing, this book lingers long after you close it.”
—Tade Thompson

“What a ride…talks like big-brained science fiction and runs like a fleet-footed political thriller.”
—John Scalzi

“Tchaikovsky has created a fantastic and highly imaginative new genre: evolution SF.”
—Peter F. Hamilton

“Unlike anything I've read in a very long time, and all the better for it…Tchaikovsky is clearly at the top of his game right now.”
—James Oswald

“As all right thinking people know, Adrian is the best…But this, my friends, is the best of the best.”
—Ian McDonald

“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
