Ancestor By Scott Sigler

Every five minutes, a transplant candidate dies while waiting for a heart, a liver, or a kidney. Imagine a technology that could provide those life saving organs for a nominal fee.....and imagine what a company would do to monopolize that technology.

On a remote island in the Canadian Arctic, P.J. Colding leads a team of scientists 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 their common ancestor. The method? Illegal. The result? A computer engineered living creature --- an animal whose organs can be permanently transplanted into anyone with zero chance of rejection.

There's just one problem: these ancestors turn out not to be the docile herd animals Colding's team envisioned. Instead, Colding's work has given birth to something big, something evil.

......AND IT'S VERY, VERY HUNGRY!
