Hybrids

In "The Neanderthal Parallax," human scientist Mary Vaughan and her Neanderthal partner Ponter Boddit face the significant challenge of conceiving a child amidst the complexities of their genetic differences. Their journey leads them to seek forbidden technology from a Neanderthal scientist in a remote wilderness, as they confront both scientific and emotional obstacles. The audiobook also includes a bonus segment where author Robert J. Sawyer shares insights into the "secret history" of the trilogy.
