Eleanor Hastings knew from experience that some bombs lie buried for decades before blowing up to do their damage. Now, 40 years after World War II, one such bomb explodes in the form of a cache of faded wartime letters that confirm the rumors that her husband, Frank, had heard all his life: he really was just a bastard that his father brought back from the war in France. The discovery sends Frank on a quest to find out who he really is - and to uncover his parents’ long-buried secrets.
