Daisy Buchanan is one of the key characters in which novel?

"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.

Daisy Buchanan is an attractive, though shallow and self-absorbed, young debutante and socialite from Louisville, Kentucky, identified as a flapper. She is Nick's second cousin once removed, and the wife of Tom Buchanan. Before she married Tom, Daisy had a romantic relationship with Gatsby. Her choice between Gatsby and Tom is one of the central conflicts in the novel. The character of Daisy is believed to have been inspired by Fitzgerald's youthful romances with Ginevra King.
