Target: Cuba — Robin Moore

From the rear cover of this 297 page book: "'The Singleton' is the inside story of an individual Special Forces operator hand selected and trained to go into harm's way, alone. The story takes place in 2004 in the midst of the U.S. War on Terrorism and the heated political environment only months prior to the U.S. presidential election. The specter of a new terrorist threat emanates from Cuba, and Special Forces Major Mike Trantor is deployed to combat Fidel Castro's finest in an amazingly complex CIA and UK/US operation. The matter is complicated by Mike's deteriorating situation at home with his wife and by a beautiful CIA operator - his closest confidante. Once on the ground, the unexpected sends Mike into an increasingly dangerous spiral as he tries to fight his way back home."
