DR. STEVEN ANDREWS is an assistant professor of paleontology at Montana State University when he is recruited for a top-secret National Security Agency job-a mission so secret that not even the President of the United States is aware of it.

The most appealing aspect of this book is the concept of cross-temporal war. The possibility of armies from separate eras duking it out in situ should entertain fans of both the novelist Harry Turtledove and the J. J. Abrams show Fringe. In the case of The Dinosaur's Descendants, humanity's complete lack of awareness of dinosaur capabilities is nearly fatal. Team T-REX doesn't even respond to any perceived danger of dinosaur time travel-they get astronomically lucky and run into it by accident.
