Author: Steve Alten
Books: MEG: A Novel of Deep Terror, The LOCH, and Domain
Imagine a book written by Michael Crichton, Peter Benchley, and Dan Brown and you would probably have a Steve Alten book. His work is an excellent mix of history, science, thriller, and science fiction.
Author: Barb & JC Hendee
Books: Dhampir, Theif of Lives, and Sister of the Dead
Barb & JC Hendee have created a wonderful fantasy world that mixes elements of Buffy the Vampire Slayer and Lord of the Rings in their Noble Dead series.
Author: Dan Brown
Books: Angels & Demons, The Da Vinci Code, and Deception Point
Dan Brown has written three of the best historical thrillers that I have ever read.
Author: Terry Brooks
Books: The Sword of Shannara, etc.
Terry Brook's Shannara series is one of the best in the world of fantasy. Yes it is very reminiscent of LOTR but who cares? It's good stuff.
