At 1 a.m. in a deserted Pennsylvania library, Nat Turnbull's cell phone rings. His former mentor, Professor Gordon Wolfe, has been arrested by the FBI for stealing top-secret archive documents dating back to the Second World War.
Coerced by the FBI into examining the archives, Nat finds intriguing references both to Wolfe's activities in an Allied intelligence office during the war and to a mysterious student resistance group in Berlin known as the White Rose.
Following Wolfe's cryptic clues to Europe, Nat uncovers a wartime story of love and betrayal that is reaching out from the past to destroy the present. Now Nat is in a desperate race to unlock the truth.
