The Great Gatsby [SEP] Introduction
The Great Gatsby is a 1925 novel written by American author F. Scott Fitzgerald that follows a cast of characters living in the fictional towns of West Egg and East Egg on prosperous Long Island in the summer of 1922. Many literary critics consider "The Great Gatsby" to be one of the greatest novels ever written. The story of the book primarily concerns the young and mysterious millionaire Jay Gatsby and his quixotic passion and obsession to reunite with his ex-lover, the beautiful former debutante Daisy Buchanan. Considered to be Fitzgerald's "magnum opus", "The Great Gatsby" explores themes of decadence, idealism, resistance to change, social upheaval and excess, creating a portrait of the Roaring Twenties that has been described as a cautionary tale regarding the American Dream.
