Basic Plot Summary-
Hemmingway, through the perspective of Jake Barnes, the narrator and central figure in the rest of the book, begins the plot of The Sun Also Rises with an extensive biography of Robert Cohn.

That winter, Cohn went to America to have his novel published. While he was there, he created a stir and was treated nicely by several women.

Jake would not agree to go.
Jake goes to a party and meets a relation, Brett, whom he met while in the war; she is described as "Damn good looking". While at the party,
