Originally published at the zenith of Nazi Germany's power, the Moon Is Down explores the effects of invasion on both the conquered and the conquerors. Occupied by enemy troops, a small, peaceable town comes face-to-face with evil imposed from the outside and betrayal from within the close-knit community. As he delves into the motivations and emotions of the enemy, Steinbeck uncovers profound and often unsettling truths both about war and human nature.
