Maine lobster fisherman Amos Coombs knows that German U-boats are hiding out along the coast by day and sinking American merchant vessels at night. Until one terrifying day, however, he is unaware that the enemy is quite literally in his backyard or that the presence of a Nazi submarine is about to change his life and those of his fellow islanders forever. More than just a war novel, this excitingly original novel presents a vivid portrayal of a community and a way of life.
