Query: Great Book by a Great Author.

Rainbow Six was a great novel that kept me thinking and plotting through the whole book. It opens up with a great action segment and introduces readers tho the main characters. Throughout the book it unfolds a great storyline of espionage and terrorism. Its action-packed and full of suspense.It is about a team of awsome military perfectionists put together by the government in case of a world crisis.The team is called Rainbow Six and is headed by John Clark, an old war veteran/espionage expert. The team travels all around the world tending to terrorist acts that the local police cant control.All in all, this book was simply amazing and i recomend it to anyone and everyone who enjoys action/suspense novels.
