The planet was unknown¿ a savagely primitive place where every man had to kill every other man - or live as a slave. The inhabitants lived in the early Bronze Age one minute, and in the early Machine Age the next. Technology had degenerated into a number of mysteries jealously guarded by separate brotherhoods. But Jason dinAlt was a gambler. He realised that if he was ever going to get a winning hand in this game, the brotherhoods would need a shuffle¿

The planet was called Felicity. The name was a joke except for those compelled to settle there. Inhabiting it were beings bred for thousands of years for a single purpose: to attack and kill. Jason dinAlt knew this, but he also knew the planet on which he lived was moving towards certain disaster. And, Felicity was the only spot in the universe where he and his companions could survive. He thought he had worked out the perfect plan. But what awaited him on Felicity went far beyond his wildest imagining.

From a Science Fiction Hall of Fame inductee, “intelligent reptiles battle stone age humans for control of an alternate Earth” (Kirkus Reviews). Sixty-five million years ago, a disastrous cataclysm eliminated three quarters of all life on Earth. Overnight, the age of dinosaurs ended. The age of mammals had begun. But what if history had happened differently? What if the reptiles had survived to evolve intelligent life? In West of Eden, bestselling author Harry Harrison has created a rich, dramatic saga of a world where the descendants of the dinosaurs struggled with a clan of humans in a battle for survival. Here is the story of Kerrick, a young hunter who grows to manhood among the dinosaurs, escaping at last to rejoin his own kind. His knowledge of their strange customs makes him the humans’ leader . . . and the dinosaurs’ greatest enemy. West of Eden is a monumental epic of love and savagery, bravery and hope. “A perfectly grand storyteller.” —David Brin, Hugo and Nebula Award–winning author of Star Tide Rising “Few commercial writers are more deserving of their popularity than Harrison, a fine writer who occasionally reaches brilliant heights.” —Publishers Weekly
