"One of the foremost science fiction writers of our generation"(SF Site) comes to Ace with a trilogy of the Web's awakening.

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. While exploring this amazing realm, she discovers something-some other-lurking in the background. And it's getting more and more intelligent with each passing day......

Hominids examines two unique species of people. We are one of those species; the other is the Neanderthals of a parallel world where they became the dominant intelligence. The Neanderthal civilization has reached heights of culture and science comparable to our own, but with radically different history, society and philosophy.

Ponter Boddit, a Neanderthal physicist, accidentally pierces the barrier between worlds and is transferred to our universe. Almost immediately recognized as a Neanderthal, but only much later as a scientist, he is quarantined and studied, alone and bewildered, a stranger in a strange land. But Ponter is also befriended—by a doctor and a physicist who share his questing intelligence, and especially by Canadian geneticist Mary Vaughan, a woman with whom he develops a special rapport.

Ponter’s partner, Adikor Huld, finds himself with a messy lab, a missing body, suspicious people all around and an explosive murder trial. How can he possibly prove his innocence when he has no idea what actually happened to Ponter?

To test his theories of immortality and life after death, Dr. Peter Hobson has created three electronic simulations of his own personality. The first has all knowledge of physical existence edited out, to simulate life after death. The second is without knowledge of aging or death, to simulate immortality. The third is unmodified, a control. Now they are free. One is a killer....

In the Hugo-Award winning Hominids, Robert J. Sawyer introduced a character readers will never forget: Ponter Boddit, a Neanderthal physicist from a parallel Earth who was whisked from his reality into ours by a quantum-computing experiment gone awry - making him the ultimate stranger in a strange land.

In that book and in its sequel, Humans, Sawyer showed us the Neanderthal version of Earth in loving detail - a tour de force of world-building; a masterpiece of alternate history.

Now, in Hybrids, Ponter Boddit and his Homo sapiens lover, geneticist Mary Vaughan, are torn between two worlds, struggling to find a way to make their star-crossed relationship work. Aided by banned Neanderthal technology, they plan to conceive the first hybrid child, a symbol of hope for the joining of their two versions of reality.

But after an experiment shows that Mary's religious faith - something completely absent in Neanderthals - is a quirk of the neurological wiring of Homo sapiens brains, Ponter and Mary must decide whether their child should be predisposed to atheism or belief. Meanwhile, as Mary's Earth is dealing with a collapse of its planetary magnetic field, her boss, the enigmatic Jock Krieger, has turned envious eyes on the unspoiled Eden that is the Neanderthal world . . .
Hybrids is filled to bursting with Sawyer's signature speculations about alternative ways of being human, exploding our preconceptions of morality and gender, of faith and love. His Neanderthal Parallax trilogy is a classic in the making, and here he brings it to a stunning, thought-provoking conclusion that's sure to make Hybrids one of the most controversial books of the year.

These very different books have only their strengths in common: imaginative originality, unique scientific extrapolation, and great stories.Hominids, the first book of the Neanderthal Parallax, is a story of parallel worlds: our own, and another in which neanderthals, not homo sapiens, became the dominant intelligent species. In that world, neanderthal civilization has reached heights of culture and science comparable to our own, but very different in detail and philosophy. During a risky physics experiment deep in a mine in Canada, a neanderthal physicist, Ponter Boddit, is accidentally transferred to our universe, where another experiment is taking place in the same mine. He is captured and studied, alone and bewildered, a stranger in a strange land. Back home, Ponters research partner is left with a messy lab, a missing body, suspicious people all around, and a murder trial that he cant possibly win because he doesnt know what happened. When luck, curiosity, imagination and inventiveness combine to save the day, its not the end at all but a new beginning, with two worlds eager to learn more about what links them and what holds them apart....
