The novel "The Great Gatsby" is one of the most important classic works in American literature, written by the novelist F. Scott Fitzgerald in 1925. Its events take place in the 1920s, a period known as the "Roaring Twenties" in the United States, where Fitzgerald describes a world of wealth, extravagance, and deceptive appearances after World War I. The novel tells the story of the mysterious young man Jay Gatsby, a rich man who hosts legendary parties in his lavish mansion hoping to win back his old love Daisy Buchanan, who is married to the arrogant wealthy Tom Buchanan. The story is narrated by Nick Carraway, Gatsby's neighbor and Daisy's cousin, who conveys to the reader the details of the conflict between dream and reality, love and betrayal, ambition and brokenness. The novel reflects the illusion of the American Dream, showing how the pursuit of money and status does not necessarily bring happiness, but can lead to disappointment and tragedy.
