This Side of Paradise: Francis Fitzgerald

Fitzgerald's first novel, This Side of Paradise (1920) was an immediate, spectacular success and established his literary reputation. Perhaps the definitive novel of the "Lost Generation," it tells the story of Amory Blaine, a handsome, wealthy Princeton student who halfheartedly involves himself in literary cults, "liberal" student activities and a series of empty flirtations with young women. When he finally does fall truly in love, however, the young woman rejects him for another.
After serving in France during the war, Blaine returns to embark on a career in advertising. Still young, but already cynical and world-weary, he exemplifies the young men and women of the 20s, described by Fitzgerald as "a new generation grown up to find all Gods dead, all wars fought, all faiths in man shaken."
