Tom Clancy invented the Techno-Thriller with The Hunt for Red October. His books are a blend of action, adventure, and technology, most often with great details about the military. His writing style is very conversational, which appeals to many readers. Clancy's books tell the stories of military men in communities of men, and women very seldom appear. His heroes are moral and patriotic, and their tales are told with a quick pace and explosive conclusions.
