The novel tells about the Corleone family and how they became one of the most powerful families in the world of crime. The action takes place in New York in 1933, during the Great Depression. Vito Corleone realizes that the time of prosperity for criminal clans is coming to an end, and prepares for a war for power. He worries about his family—especially his children, who are still too young to understand the dangers they face. The eldest son, Sonny, already dreams of joining his father’s business, but his rash actions may lead to unforeseen consequences.
