Query: Great Cold War/SF Adventure!

Fantastic book about a fictional time when Texas stands against the might of the Russians. Ripley Forte is the perfect hero of the day. Texas shines as the centerpiece of the novel, because she is truly a state where this might have happened. No its not the best novel ever written, but its catchy, exciting, a little intrigue, just the sort of thing for a great summer read. One Caveat, while the books can be read apart, the best read is in unison. Get all three and enjoy the show.
