content: Now and then, a good writer writes a bad book. This is one such. "Rainbow Six" is Clancy's second book about John Clark, an unromantic CIA agent with a license to kill. His first, "Without Remorse", built the character of Clark, and was perhaps Clancy's best writing. "Without Remorse" wasn't a techno-thriller, but more of a classic character novel. "Rainbow Six" is more a classic Clancy gadget story, but unlike his Jack Ryan novels, this time he can't pull the threads of unlikely events together into a believable whole. The book revolves around a succession of terrorist plots executed for no visible reason, and when the reason finally becomes clear, it doesn't make sense, especially since the bad guys aren't portrayed as dumb.I wonder if Clancy even wrote this turkey. It reads more like the "Op-Center" books, on which he puts his name but doesn't write.
