What makes a Human?

A frozen world on the edge of civilized space has a deadly secret. The indigenous people, known as the Ixtyl were human-looking to be sure, but they had characteristics so unique there was doubt they were naturally acquired. Human? Or genetically modified creatures? Humans, including Indigenous peoples, were heavily protected by law. Genetically modified creatures were not. They were like lab rats who would have no rights, no hope, and no future. The tribe lives on a planet rich with an invaluable ore: One men are willing to kill for. When Certified Genomist Damien Durne is called to investigate the Ixtyl’s genome, to certify whether they are human or not, he is flung into an intrigue of lies and murder, with an ultimate goal of genocide.
