W. E. B. Griffin's OSS heroes face two extraordinary challenges in the latest addition to the New York Times-bestselling series.

Summer 1943. Two of the Allies' most important plans for winning World War II are at grave risk-Operation Overlord for the invasion of France, and the Manhattan Project in the race to build the atomic bomb. A furious FDR turns to OSS spy chief "Wild Bill" Donovan-and Donovan turns to his top agent, Dick Canidy, and his team.

They've certainly got their work cut out for them. In the weeks to come, they must fight not just the enemy in the field-and figure out how to sabotage Germany's new "aerial torpedo" rockets-but also the enemy within: someone is feeding the Manhattan Project secrets to the Soviets. Moles are bad enough. Yet if the Soviets build their own atomic bomb . . . who knows where that might lead?
