"A gripping adventure story of prehistoric men and women facing fearful odds... should appeal to readers who have enjoyed Jean Auel's The Clan of the Cave Bear and The Valley of Horses." - Fritz Leiber

"West of Eden is truly a bravura performance.  I predict that its popularity will rival Dune, to which I consider it superior as a totally realized extrapolation." - Thomas N. Scortia

"West of Eden is Harrison's best book in years, inventive, engrossing, and solidly based on what might have been." - Ben Bova

Sixty-five million years ago, a disastrous cataclysm exterminated three quarters of all species on earth.  Overnight the age of dinosaurs was ended: the age of mammals had begun.

But if that disaster had never happened and the dinosaurs had survived to fulfill their evolutionary destiny, this is what the world might have been.  The world West of Eden.

Harry Harrison, a modern master of imaginative fiction, has created a gripping, vividly rendered epic of prehistory about the tragic, inevitable clash of two mighty races: the Yilane, cold-blooded intelligent reptiles who have dominated the earth and the Tanu, warm blooded humans like ourselves, a proud, fierce hunting clan destined to oppose them.

West of Eden is the remarkable odyssey of Kerrick, a young Tanu hunter captured by the Yilane and raised as one of them by their ruthless matriarch.  As he grows to manhood, Kerrick is schooled in the strange customs, exotic biological sciences, and rigid caste structure of Yilane culture, and for a time all but forgets his heritage.

When at last he escapes and rejoins his people, Kerrick is at first an outcast.  Then, among his tribesmen, he finds love and begins a family, and rises to become the leader of the Tanu.  As Yilane raids threaten the future of the Tanu, Kerrick leads his clan on an arduous trek to unite the human tribes in a confrontation with their enemy that will alter forever the course of history.

A fascinating and deeply moving saga of two cultures fated to struggle for control of the earth,  West of Eden is also a scientifically accurate projection of what could have been the true history of our world.  Throughout this powerful story, and in a detailed appendix, "The World West of Eden,"
