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 into intelligent life? In West of Eden, best-selling 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.

Paleontologist Brandon Thackery and his rival, Miles "Klicks" Jordan, fulfill a dinosaur lover's dream with history's first time-travel jaunt to the late Mesozoic. Hoping to solve the extinction mystery, they find Earth's gravity is only half its 21st-century value and dinosaurs that behave very strangely. Could the slimy blue creatures from Mars have something to do with both?

Neanderthals have developed a radically different civilization on a parallel Earth. A Neanderthal physicist, Ponter Boddit, accidentally passes from his universe into a Canadian underground research facility. Fortunately, a team of human scientists, including expert paleo-anthropologist Mary Vaughan, promptly identifies and warmly receives Ponter. Solving the language problem and much else is a mini-computer, called a Companion, implanted in the brain of every Neanderthal. But it can't help his fellow scientist back in his world, Adikor Huld, when the authorities charge Adikor with his murder.

Experimental psychologist Jim Marchuk has developed a flawless technique for identifying the previously undetected psychopaths lurking everywhere in society. But while being cross-examined about his breakthrough in court, Jim is shocked to discover that he has lost his memories of six months of his life from 20 years previously - a dark time during which he himself committed heinous acts.

While J. Robert Oppenheimer and his Manhattan Project team struggle to develop the A-bomb, Edward Teller wants something even more devastating: a weapon based on nuclear fusion - the mechanism that powers the sun. But Teller’s research leads to a terrifying discovery: by the year 2030, the sun will eject its outermost layer, destroying the entire inner solar system - including Earth. After the war ends, Oppenheimer’s physicists combine forces with Albert Einstein, computing pioneer John von Neumann, and rocket designer Wernher von Braun.

In this Hugo-nominated novel, an alien walks into a museum and asks if he can see a paleontologist. But the arachnid ET hasn't come aboard a rowboat with the Pope and Stephen Hawking (although His Holiness does request an audience later). Landing at the Royal Ontario Museum in Toronto, the spacefarer, Hollus, asks to compare notes on mass extinctions with resident dino-scientist Thomas Jericho.

Caitlin Decter is young, pretty, feisty, a genius at math - and blind. Still, she can surf the net with the best of them, following its complex paths clearly in her mind. But Caitlin's brain long ago co-opted her primary visual cortex to help her navigate online. So when she receives an implant to restore her sight, instead of seeing reality, the landscape of the World Wide Web explodes into her consciousness, spreading out all around her in a riot of colors and shapes.

When prospector Bob Broadhead went out to Gateway on the Heechee spacecraft, he decided he would know which was the right mission to make him his fortune. Three missions later, now famous and permanently rich, Robinette Broadhead has to face what happened to him and what he is...in a journey into himself as perilous and even more horrifying than the nightmare trip through the interstellar void that he drove himself to take!

In the near future, a signal is detected coming from the Alpha Centauri system. Mysterious, unintelligible data streams in for ten years. Heather Davis, a professor in the University of Toronto psychology department, has devoted her career to deciphering the message. Her estranged husband, Kyle, is working on the development of artificial intelligence systems and new computer technology utilizing quantum effects to produce a near-infinite number of calculations simultaneously.

When a disabled spaceship enters Earth's atmosphere, seven members of the advanced Tosok race are welcomed by the world. Then a popular scientist is murdered, and all evidence points to one of the Tosoks. Now, an alien is tried in a court of law -and there may be far more at stake than accounting for one human life.

A pair of fierce but beautiful eyes look out from the undergrowth of conifers. The eyes follow every movement in the great herd of plant-eating dinosaurs that mills around the open meadows, moving back and forth with the rapid scanning of a hunter who is thinking about everything she sees. She is an intelligent killer.

Harry August is on his deathbed. Again. No matter what he does or the decisions he makes, when death comes, Harry always returns to where he began, a child with all the knowledge of a life he has already lived a dozen times before.

This is the story of what Harry does next, and what he did before, and how he tries to save a past he cannot change and a future he cannot allow.

Jake Sullivan has cheated death: he's discarded his doomed biological body and copied his consciousness into an android form. The new Jake soon finds love, something that eluded him when he was encased in flesh: he falls for the android version of Karen, a woman rediscovering all the joys of life now that she too is no longer constrained by a worn-out body. Karen's son sues her, claiming that by uploading into an immortal body, she has done him out of his inheritance.

Stranger in a Strange Land is the epic saga of an earthling, Valentine Michael Smith, born and educated on Mars, who arrives on our planet with “psi” powers—telepathy, clairvoyance, precognition, telekinesis, teleportation, pyrolysis, and the ability to take control of the minds of others—and complete innocence regarding the mores of man. After his tutelage under a surrogate father figure, Valentine begins his transformation into a kind of messiah.

I'm the one and only private eye working the mean streets of New Klondike, the Martian frontier town that sprang up forty years ago after Simon Weingarten and Denny O'Reilly discovered fossils on the Red Planet.
