I've recently discovered W.E.B.Griffin. He's sort of a political suspense thriller writer like Robert Ludlum. Griffin has two books w/the same character, a young FBI/Homeland Security agent whose name escapes me. The titles are By Order of the President and The Hostage. I found I couldn't put these books down.
Another thriller/suspense author is Greg Iles. I've read The Quiet Game and Turning Angel. These books also share the same characters and are set in Iles' birthplace, Natchez,Mississippi. They are murder mysteries and the evil specter of racism raises its ugly head. After reading these books, I wonder whether Iles truly portrays race relations in Natchez as they are or if he takes literary license.
I just finished Mary, Mary by James Patterson. The most recent novel in his Alex Cross series. Alex is a cop who solves serial murders. I've read every single book in this series. Some are better than others but all keep me enthralled until the last page.
