Ancestor

"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.
