"The ancestors are out there...you have to believe me." From acclaimed author Scott Sigler-- New York Times bestselling creator of Infected and Contagious --comes a tale of genetic experimentation's worst nightmare come true.   Every five minutes, a transplant candidate dies while waiting for a heart, a liver, a kidney.  Imagine a technology that could provide those life-saving transplant organs for a nominal fee ... and imagine what a company would do to get a monopoly on that technology.   On a remote island in the Canadian Arctic, PJ Colding leads a group of geneticists who have discovered this holy grail of medicine. By reverse-engineering the genomes of thousands of mammals, Colding's team has dialed back the evolutionary clock to re-create humankind's common ancestor. The method? Illegal. The result? A computer-engineered living creature, an animal whose organs can be implanted in any person, and with no chance of transplant rejection.   There's just one problem: these  ancestors  are not the docile herd animals that Colding's team envisioned. Instead, Colding's work has given birth to something big, something  evil .   With these killer creatures on the prowl, Colding and the woman he loves must fight to survive -- even as government agents close in to shut the project down, and the deep-pocketed company backing this research proves to have its own cold-blooded agenda.     As the creators become the prey in the ultimate battle for survival, Scott Sigler takes readers on the ultimate thrill-ride--and offers a chilling cautionary account of what can happen when hubris, greed, and madness drive scientific experimentation past the brink of reason.
