F. Scott Fitzgerald's The Great Gatsby explores the 1920s era in America known as the "Jazz Age." The novel depicts the decadence and excess of the era through its main characters, who represent both "old money" and "new money." The green light at the end of Daisy's dock symbolizes Gatsby's hopes and dreams for rekindling his romance with Daisy. The story serves as a critique of the era and its fading American Dream.
