Jay Gatsby is a young millionaire (born in a poor family) with mysterious quixotic passion for the beautiful woman Daisy Buchanan. The story explores the social change with decadence, idealism, resistance to change and excesses. It creates a portrait of the Jazz Age or the Roaring Twenties. The novel is a cautionary tale regarding the upheavals created by the disastrous cultural changes in the American society in that period.
