Summary
Analysis
After the funeral for Michael Holtzapfel, Liesel reads The Dream Carrier to Frau Holtzapfel as usual. Death describes how busy he is with the Allies' bombing of Hamburg. Hitler is starting to lose the war, but he doesn't scale back the fighting or the murder of Jews.
The war is starting to wind down, but the danger has only increased for the characters of the novel. By this point Death seems more and more weary of his work, and horrified at the terrible things humans do to each other.
