Publisher's Summary

“The ancestors are out there…you have to believe me.”
From acclaimed author Scott Sigler—New York Times best-selling 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, P. J. 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 listeners 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.


What the Critics Say

“A tremendously entertaining horror novel…the premise is thought-provoking; Sigler populates the novel with a lively cast of characters (unlike many thrillers, the heroes are as interesting as the villains), and the action is virtually nonstop—and, at times, quite graphic. If you combined Michael Crichton’s scientific exploration with Matthew Reilly’s lightning-fast pace and colorful characters, you might get something that feels like this book, which, incidentally, would make a great movie.” ( Booklist)

Scott Sigler = best modern horror writer

What made the experience of listening to Ancestor the most enjoyable?

Scott Sigler narrates his own books which in some writers case would be a bad thing, but scott puts effort into his "performance" every character gets a different voice, all of which are pretty decent actually, his female voices are below the rest but he is fully aware of this and tries his best. Surprisingly it actually makes the book come to life.

What did you like best about this story?

its a blend of Jurassic park( the book) and the film Dog Solders, in other words the story kicks major behind.

Have you listened to any of Scott Sigler’s other performances? How does this one compare?

This is my favorite Scott sigler performance, his later books improve his female voices but this one is the best story

If you made a film of this book, what would be the tag line be?

"On an Island where man plays god,Mankind is about to become an endangered species"

I'm Scott Sigler's new biggest fan, it's sci-fi, horror, real life. He's influenced by Stephen King and it shows but he's completely go his own voice and style. I absolutely love it and am eagerly awaiting the next book. I love the fact the author narrates them. The characters are real and likeable, the action is fast paced, it's gripping. The science is sound without getting confusing (for those of us who aren't too clued up). It's great, just buy it! No wait, it's a sequel, just buy everything he has written that you can get your hands on.
