The ANCESTOR fan-generated video above was directed, shot, cut and composed by Adrian Picardi of Aureus Grex. It was shot from a script written by Scott Sigler, which was adapted out of a scene from the novel. 

“Fun, creepy, and impossible to stop reading, Ancestor is the rare thriller that’s based on cutting-edge science and is entirely possible. Long after you’re done with the book, you’ll still be looking over your shoulder. Just in case.”
Phil Plait, PhD, author of DEATH FROM THE SKIES and creator of


“The ancestors are out there … you have to believe me.”

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.

“This story sizzles with tension. Danger and drama mix with cutting-edge science to produce a top notch, action-packed adventure. If you think Scott Sigler just writes horror, you’re dead wrong. This guy is one heck of a thriller writer.”
Steve Berry, New York Times bestselling author of THE PARIS VENDETTA and THE CHARLEMAGNE PURSUIT

“Michael Crichton may be gone, but he has a worthy successor in Scott. This book takes thriller and science fiction conventions and slams them together to make something new and fascinating.”
Simon R. Green, New York Times bestselling author of THE GOOD, THE BAD, AND THE UNCANNY and AGENTS OF LIGHT AND DARKNESS

“Sigler has a unique talent for keeping readers on the edge of their seats; I absolutely had to know what was going to happen next. Infected is full of mayhem, action, and gore — and you won’t be able to put it down.”
Dave Wellington, author of 13 BULLETS and the MONSTER ISLAND trilogy
