Robert J. Sawyer's Hominids , the first volume of his bestselling Neanderthal Parallax trilogy, won the 2003 Hugo Award, and its sequel, Humans , was a 2004 Hugo nominee. Now he's back with a pulse-pounding, mind-expanding standalone novel, rich with his signature philosophical and ethical speculations, all grounded in cutting-edge science.
Jake Sullivan has cheated 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 he falls for the android version of Karen, a woman rediscovering all the joys of life now that she's no longer constrained by a worn-out body either.
But suddenly Karen's son sues her, claiming that by uploading into an immortal body, she has done him out of his inheritance. Even worse, the original version of Jake, consigned to die on the far side of the moon, has taken hostages there, demanding the return of his rights of personhood. In the courtroom and on the lunar surface, the future of uploaded humanity hangs in the balance.
Mindscan is vintage Sawyer -- a feast for the mind and the heart.

Dr. Sarah Halifax decoded the first-ever radio transmission received from aliens. Thirty-eight years later, a second message is received and Sarah, now 87, may hold the key to deciphering this one, too . . . if she lives long enough. A wealthy industrialist offers to pay for Sarah to have a rollback―a hugely expensive experimental rejuvenation procedure. She accepts on condition that Don, her husband of sixty years, gets a rollback, too. The process works for Don, making him physically twenty-five again. But in a tragic twist, the rollback fails for Sarah, leaving her in her eighties. While Don tries to deal with his newfound youth and the suddenly vast age gap between him and his wife, Sarah struggles to do again what she'd done once figure out what a signal from the stars contains.

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. A computerized guardian spirit, however, doesn't eliminate cross-cultural confusion; permanent male-female sexuality, rape, and overpopulation are all alien to Ponter. Nor can it help his housemate and fellow scientist back in his world, Adikor Huld, when the authorities charge Adikor with his murder.

An alien shuttle craft lands outside the Royal Ontario Museum in Toronto. Out pops a six-legged, two-armed alien, who says, in perfect English, "Take me to a paleontologist."

It seems that Earth, and the alien's home planet, and the home planet of another alien species traveling on the alien mother ship, all experienced the same five cataclysmic events at about the same time, including events exactly like the meteor that wiped out the dinosaurs. Both alien races believe this proves the existence of God: i.e. he's obviously been manipulating the evolution of life on each of these planets.

FLASHFORWARD

Two minutes and seventeen seconds that changed the world

Suddenly, without warning, all seven billion people on Earth black out for more than two minutes. Millions die as planes fall from the sky, people tumble down staircases, and cars plow into each other.

But that’s the least of the survivors’ challenges. During the blackout, everyone experienced a glimpse of what his or her future holds—and the interlocking mosaic of these visions threatens to unravel the present.

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.

When Heather achieves a breakthrough, the message reveals a startling new technology that rips the barriers of space and time, holding the promise of a new stage of human evolution. In concert with Kyle's discoveries of the nature of consciousness, the key to limitless exploration---or the end of the human race---appears close at hand.

Sawyer has created a gripping thriller, a pulse-pounding tour of the farthest reaches of technology.  Factoring Humanity is a 1999 Hugo Award Nominee for Best Novel.
