New York Times bestselling thrill-master James Rollins is back with The Devil Colony (On Sale 6/21), another electrifying combination of suspense, history, science, action, and ingenious speculation. In The Devil Colony, Sigma Force stalwarts Painter Crowe and Commander Grayson Pierce must investigate a gruesome massacre in the Rocky Mountains and root out a secret cabal that has been manipulating momentous events since the time of the original thirteen colonies. Once again, Rollins delivers a spine-tingler that will leave fans of Michael Crichton, The Da Vinci Code, and Indiana Jones breathless—as he exposes the dark truth behind the founding of America.

James Rollins fans can read an exclusive excerpt of The Devil Colony among other book Excerpts, as well as get a free Map of Bones audio download. There are Polls where fans are asked If bad guys burst into the room, you are most likely to? and Which Sigma Member Are You?, several Quizzes that test fans’ knowledge of Rollins’ books, and book-related virtual gifts to share with friends.
