Summary
Analysis
In April Hans is discharged from the hospital. He comes home at night and everyone is overjoyed, and he tells Liesel and Rosa the details of his experience in the LSE. That night he sits with Liesel while she sleeps. Liesel enjoys three months of happiness then, but Death forebodes that it will not last.
There is another respite from the grimness of war with this happy homecoming. Hans and Liesel have been favored by fate for now, but Death as usual warns of bad luck to come.
