I pretty much read only non fiction, which I think are much more interesting than anything anyone can make up. Plus the writing skill is so much better.
I you want to read about a real T-Man try Peter the Great by Robert K. Massie
I do like some fiction Authors
Tom Wolfe - A Man in Full (long book)
I used to really like the Spenser detective books by Robert Parker - Tough guy Boston PI
Clive Cussler - undersea adventures with Dirk Pit
I'm really not familiar with any current hot authors. I have really not seen anything in B&N that would interest me
