Humans

Robert J. Sawyer, the award--winning and bestselling writer, hits the peak of his powers in Humans, the second book of The Neanderthal Parallax, his trilogy about our world and another parallel one in which it was the Homo sapiens who died out and the Neanderthals who became the dominant intelligent species. Now, Neanderthal physicist Ponter Boddit, a character you will never forget, returns to our world and to his relationship with geneticist Mary Vaughan. As cultural exchanges between the two Earths begin, we experience the bursts of wonder and enlightenment that are the finest pleasures of science fiction.
