"The back of the book labels "The Rock" as a science thriller. This is an accurate description as it's a combination of science fiction and techno-thriller. While similar to his other books (Area 51, Atlantis, etc. -- published under a pseudonym), this one grabs you at the beginning and doesn't let go.Five people from across the planet are summoned to a secretive meeting with no idea of what is to happen. They soon learn that a transmission has been received with their names included. Other scientists, the military, the Russians and the President eventually get involved. What results is a race against time to preserve the future of the human race. The resolution is well presented and has a definite sci-fi feel to it.If you enjoy the other novels by this author, you will definitely enjoy this one as well. It's a quick and easy read that can be completed in one sitting. If you find this work entertaining, check out the novels by James Rollins for other "science thriller" works."
