I have never been all that interested in military literature. However, I found Red Tide quite enjoyable. Mr. Kennedy makes it sound quite plausible that, given the proper planning, a foreign power could sweep in and occupy an American metropolitan area, thereby crippling the rest of the country (at least for a period of time). The big questions are how will the U.S. respond and can the threat be erradicated? I recommend Red Tide not only to fans of military literature, but also to devotees of thrillers and page turners.
