I've really enjoyed the Joe Pickett (he's a game warden in Montana) series by CJ Box.

I'm also a fan of W.E.B. Griffins different series.

Larry McMurtry wrote a LOT of good books besides the Lonesome Dove series, though the namesake book is one of the best I've ever read.

Read a lot of Pat Conroy's books but they're mostly depressingly dark.
