ANCESTOR

by Scott Sigler

4****

While trying to make a human transplant breakthrough, geneticists create a new animal. The "ancestor" to all mammals on earth. The ancestor is not as safe and docile as expected. Add in a psychopath boss who wants anybody involved in the project dead.

It takes a little while for the action to start, but it is non stop once it starts.

I listened to this book on audiobook read by Scott Sigler himself. He used a different voice/accent for each character, and really lets you see their personalities.
