What would thriller writers do without the Nazis? At the start of Rollins's inventive eighth Sigma Force novel, a secret experiment is smuggled out of Berlin in the waning days of WWII. While the Americans have been working on the atomic bomb, the Nazis were delving into the paradoxical tenets of quantum mechanics. In the present day, descendants of Heinrich Himmler are trying to create a new race of Aryan supermen. Last seen in 2005's Map of Bones, Painter Crowe and Grayson Pierce, employees of Sigma Force, a secret arm of the U.S. military, venture to the brink of death to puzzle out mysteries that encompass the theories of evolution, intelligent design, and the physical and spiritual nature of love and God. It's a tall order, but every time the author appears to have stretched too far, he saves the read by throwing in a fascinating scientific or historical fact, plus a scene of heart-pumping action. This is Cussler and Ludlum territory with a dash of Dan Brown, sure to please devotees of any of these authors.
