If you have read many of the Oregon Files based books by Clive Cussler, you have a feel for the general style and format that he follows. That style and format produces very entertaining stories that make the books hard to put down. Shadow Tyrants certainly delivers an entertaining story following the Cussler format. The familiar characters do their usual cliff hanger save the world thing, and keep you engaged in the process. The foundation for the story is a bit different this time around and produces some very interesting situations for the "good guys". A most enjoyable read.
