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.

Twenty years after the discovery of artificial wormholes launches Earth space exploration to unforeseeable heights, Starplex Director Keith Lansing investigates a mysterious vessel that soon threatens the station with intergalactic war.

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.

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.

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.

Thirty-eight years ago, Dr. Sarah Halifax earned worldwide fame by deciphering a radio transmission from an unknown intelligence reaching out from deep space. Now 87, Sarah receives news that, at long last, a new signal has been received, and her services are desperately needed once again.

This is the story of Pierre Tradivel, a scientist, and his complex battle against deadly illness, and ex-Nazi war criminal still hiding in the U.S., a crooked insurance company, and a plot to make Pierre and his wife the victims of a bizarre genetic experiment. Frameshift is hard science fiction at its best, full of complications and neat surprises.

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.  

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.

Welga Ramirez, executive bodyguard and ex-special forces, is about to retire early when her client is killed in front of her. It’s, 2095 and people don’t usually die from violence. Humanity is entirely dependent on pills that not only help them stay alive but allow them to compete with artificial intelligence in an increasingly competitive gig economy. Daily doses protect against designer diseases, flow enhances focus, zips and buffs enhance physical strength and speed, and juvers speed the healing process.

A robopsychologist must outwit a machine determined to stay hidden in "Little Lost Robot"; a woman’s talent for "Light Verse" overshadows her true accomplishments with her robot servants; "The Last Question" presented to computer after computer over a hundred billion years may remain forever unanswered … and seventeen more future visions from the grand master of science fiction.

One night when he was 10, Tyler stood in his backyard and watched the stars go out. They flared into brilliance, then disappeared, replaced by an empty black barrier. He and his best friends, Jason and Diane Lawton, had seen what became known as the Big Blackout. It would shape their lives.

In 2004, Doctor Damien Howard's 131st birthday celebration took an unexpected turn. His personal SETI project detected an extraterrestrial signal directed at Earth. Unfortunately, Dr. Howard's long-hoped-for communication contained a message of dire warning rather than greeting. In 1945, humanity had become a species of galactic interest and was given 100 years to address the issue.

Though perhaps most famous as a novelist, Philip K. Dick wrote more than 100 short stories over the course of his career, each as mind-bending and genre-defining as his longer works. Philip K. Dick's Electric Dreams collects 10 of the best. In "Autofac," Dick shows us one of the earliest examples (and warnings) in science fiction of self-replicating machines. "Exhibit Piece" and "The Commuter" feature Dick exploring one of his favorite themes: the shifting nature of reality and whether it is even possible to perceive the world as it truly exists.
