Mead parachuted into Normandy on D-Day and fought his way to Germany, through some of the most brutal violence of World War II. But his most difficult battle was lost years later, when his beloved wife Sophie succumbed to cancer. Since then, he has waged a private war against both loneliness and the terrible memory of a day in 1945 that went horribly wrong-and has haunted him ever since.

His grandson Andrew, a scared and angry high school sophomore, has been expelled and is heading down a path of self-destruction. Mead agrees to take the boy in for three weeks, to set him right. At first, the two circle warily around each other, finding little in common. Then Andrew befriends a widow named Evelyn, and Mead busies himself fending off the match, even as he feels a reluctant attraction to this cheerful woman who seems to understand his grandson.

One afternoon, rummaging through the garage, Andrew discovers an antique Luger, the deadly memento of his grandfather's war. In a final effort to save his grandson from himself, Mead takes the teenager on a journey to the beaches, bunkers, and cemeteries of Normandy, where both of them confront the secrets they have been trying to forget.
