"The Nightingale's Song"
About a group of military men, such as John McCain, John Poindexter, and Oliver North. It's a beautiful insight into what makes these guys tick. McCain, for instance, was an authority defying screwup. The typical underachiever. Poindexter, sharp mind, but dedicated to the military. Ollie North meathead Marine.
These guys are all very different now, not surprising considering what they have been through.

All republicans, of course.
