From Publishers Weekly
Canadian writer Sawyer brings his Neanderthal Parallax trilogy to a close, leaving some loose ends that beg for a follow-up further exploring the interaction of two parallel worlds: the overcrowded and polluted one we're used to and another inhabited by highly intelligent and civilized Neanderthals. In the earlier books (Hominids and Humans), physicist Ponter Boddit got translated from the Neanderthal world to ours, where he fell in love with geneticist Mary Vaughn. The couple joined with people of good will from both worlds to keep the link open. Now, though, it's time to consider the implications of such a continuing connection. If people have trouble getting along because of such distinctions as sex and race, how will they be able to co-exist with members of another species? Some individuals see anyone different as a rival, a threat that must be destroyed. Others coldly calculate how to seize new territory for "humanity." Sawyer's characters are less interesting for who they are than for what they are-or what they represent. Still, his picture of the unspoiled Neanderthal world is charming, and he raises some provocative questions. If, for example, only Earth-humans have brains capable of religious belief, should Ponter and Mary genetically design their child with that ability or not? It all amounts to some of the most outrageous, stimulating speculation since Robert A. Heinlein's Stranger in a Strange Land questioned our tired, timid conventions.Copyright 2003 Reed Business Information, Inc.


From Booklist
In the conclusion of the Neanderthal Parallax trilogy (Hominids, 2002, and Humans [BKL Ja 1 & 15 03] precede it), scientists and lovers Mary Vaughan, who is human, and Ponter Boddit, who is Neanderthal, embark on the harrowing adventure of conceiving a child together. To overcome the genetic barbed wire of mismatched chromosomes, they must use banned technology obtainable only from a Neanderthal scientist living in the northern wilderness, alone but not isolated, for Neanderthals prefer a nonprivate society in which injured persons are quickly rescued, theft is unknown, and personal violence is contained, thanks to permanently implanted personal monitors--a society whose benefits Sawyer persuasively describes. The Neanderthals' electronic surveillance is compatible with their basic peacefulness, however, and can't begin to cope with human craftiness or the malevolent racism of one of Mary's colleagues, who considers Ponter's world as a plum ripe for picking. If his ambitions constitute one alarming threat to a society, the imminent collapse of Earth's magnetic field constitutes another, for it is feared that this will wreak havoc with human consciousness. In an excellent closing twist, a New Year's celebration is disrupted in a very alarming, uniquely human manner as a few Neanderthals watch dumbfounded. A fine combination of love story, social commentary, and ecothriller closes a terrific series with a bang. Roberta Johnson

Review
"Sawyer fashions a consistent, engaging, logical history and society for his Neaanderthals. . . . All in all, it's an anthropological creation worthy of Le Guin."


Review
"The genre's northern star-in fact, one of the hottest SF writers anywhere."
-Maclean's Magazine

"Hi-tech Neanderthals from a parallel continuum, with a social system like none we ever heard of. Can two very different people bridge that gap? While our world begins changes we can only try to understand. In Humans, Sawyer gives us a rich mix of mind-stretching concepts and personal crises."
--F. M. Busby

"Sawyer has carried the banner of Asimovian science-fiction into the twenty-first century. Hominids is based in cutting-edge contemporary science--paleoanthropology, quantum computing, neutrino astronomy, among others--and furnished at the same time with touching human (and parahuman) stories. Precise, detailed, and accomplished. The next volume is eagerly anticipated."
-- Robert Charles Wilson

"Robert Sawyer hits another SF homerun with Hominids: an utterly intriguing conceptual seed, state-of-the-scientific-arts theory, challenging social consciousness, and characters you want to take home for dinner."
--Jane Fancher



Book Description
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.

FROM OUR EDITORS

The Barnes & Noble Review
Hybrids is the dramatic conclusion to Robert J. Sawyer's Neanderthal Parallax trilogy (following Hominids and Humans), a saga with a bold premise: 40,000 years ago, the universe split into two parallel timelines, one where civilization evolved to where it is today (overpopulation, global warming, nuclear warfare, terrorism, Burger King, etc.) and another where the Neanderthals weren't displaced by the Cro-Magnons and survived to the present day with their own unique culture and technology. On this planet, where Homo sapiens never existed, the Neanderthals live in a highly advanced, peaceful, idyllic world with hardly any crime, disease, or pollution.

The first two novels chronicle the very first interactions between worlds -- and species -- when a an experiment goes awry and a portal is accidentally opened by a Barast (Neanderthal) quantum physicist, Ponter Boddit. In Hybrids, strong interpersonal relationships have formed between Gliksins (Homo sapiens) and Barasts. In fact, Ponter and geneticist Mary Vaughan have fallen in love and are trying to have a hybrid baby. More and more, Gliksins and Barasts are visiting each other's worlds. Technologies and ideas are being exchanged. But then the ugly side of humanity rears its head.

Like some of Sawyer's previous works (Factoring Humanity and Calculating God), Hybrids (and the entire Neanderthal Parallax trilogy, for that matter) is fodder for hours of lively debate. Just how advanced is humankind? Does God really exist? How tenable is organized religion when viewed through the eyes of an alien, intelligent species? Morality, gender issues, politics, faith, and genetic engineering -- nothing is off limits in this fantastic, thought-provoking trilogy. Paul Goat Allen
