While the book doesn't explicitly state a precise year, the time period is evident from the context:
* The presence of the Korean War: Homer, the protagonist, is a Korean War veteran, hinting at the book's setting after the war (1953).
* Social and cultural references: The presence of segregation and the lack of easy access to modern amenities like telephones suggest the book's setting is prior to the Civil Rights movement gaining significant momentum in the mid-1960s.
* Technological advancements: The use of a car, although not readily accessible to everyone, points to a time when automobiles were becoming increasingly common, further suggesting the late 1950s or early 1960s.
The setting of the Arizona desert is central to the story. The harsh landscape reflects the struggles of the characters, and the isolation of the location emphasizes the importance of community and compassion.
