This is a Kurt Austin novel. When Dirk got promoted Cussler produced a whole new set of younger heros. Kurt is the leader. He's backed up by Joe Zavala, and supported by a cast of NUMA scientists and engineers. They are every bit as good as the old crew.
This is typical Cussler, if such a mundane word can ever be used when referring to a Cussler novel. You've got ancient Phoenicians, mercenaries, early American presidents, archaeologists, librarians, and evil galore. It's another book you won't want to put down. Highly recommended.
