I have lots of favorites and they seem to shift a bit as time goes on. For main stream, quirky and odd, I like Jim Butcher's "Dresden Files" and Jennifer Estep's "Elemental Assassin" series of books; For thriller and bang, bang, shoot em’ up, Vince Flynn and Mark Greaney are both excellent; Brandon Sanderson writes excellent fantasy books and I have read most of his stories at least twice. I think it’s a tribute to the Brandon when Robert Jordan’s (king of the epic fantasy book) wife selected him to finish the “Wheel of Time” books. I would have to pick Ken Follett as one of my all time favorite authors.
Jamie DeValen’s series The Scrolls of Icaria is an exceptional body of work and just a damn fine story. I just pray he’ll finish the story.
On the Gay Author’s website I like dkstories’s work and my favorite is Mark Arbor. Mark writes some of the best dialog I have ever read. It is very difficult to feel like you are actually part of a conversation as you read it, and he does that very well. I like Reddirtwriter’s work mostly because follows along the same vein as the Walt Longmier series by Craig Johnson (another favorite mainstream writer). I have re-read the stories by Dom Luka, Jack Scribbe and David McLeod many times and they are still great reads.
