In Hominids, Robert J. Sawyer introduced a character listeners 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. 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 . . . Filled to bursting with his signature speculations about alternative ways of being human, exploding our preconceptions of morality and gender, of faith and love, Sawyer s Neanderthal Parallax trilogy is a classic in the making, and here he brings it to a stunning, thought-provoking conclusion.
