Hmmm,

Stephen Hunter, Vince Flynn, Carl Hiaasen, Clive Cussler, Tom Clancy, Dale Brown, Nelson Demille, Stephen Coonts.

I love early Stephen King and Koontz, but their styles changed a few years back. I like the supernatural terror like in The Stand, Dead Zone and The Tommyknockers-after a while it got to be too predictible.

If you like mystery/scary read Robert McCammon's Swan song-like The Stand, by King.

If you like intense crime, try Shane Steven's By Reason of Insanity.

Hannibal Lecter was a wuss compared to the Thomas Bishop character. This has to be the best crime novel/serial killer book ever written.
