Shayla, an Earth woman, who finds life on Earth hardly worth living after being deceived by her husband, and having her only son die, is close to suicide.
Ty, having lived through a plague that killed all the females on his planet, finds refuge in his work, mining a mineral instrumental to all aspect of life on Aztara, including telepathy, longevity, and levitation.
Scientists from Surtees, a dying planet, relocate to Aztara to receive the benefits of phyrium. In their attempt to rebuild the Aztarian population, they import Earth women who carry a particular gene, the warrior gene, to mate with the Aztarian men.
The story is about finding love, trust and internal strength as well as romance, intrigue, and thrills while the two main characters come to grips with a situation, not of their own choosing.
