ANCESTOR is available in hardcover ( click here to order online ), and as a serialized podcast.

Acclaimed author Scott Sigler, New York Times bestselling creator of INFECTED and CONTAGIOUS , offers a chilling tale of what can happen when hubris, greed, and madness drive scientific experimentation past the brink of reason.

Every five minutes, a transplant candidate dies while waiting for a compatible 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 monopolize 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 thousands of animal genomes, Colding's team has dialed back the evolutionary clock and re-created the progenitor of all mammals. The method? Illegal. The result? A computer-engineered living creature, an animal whose organs can be implanted in any person, 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, the work has given birth to something big, something evil … something very, very hungry.

As creators become prey in an ultimate battle for survival, 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 reveals its own cold-blooded agenda.
