Fear of Flying is a 1973 novel by Erica Jong which became famously controversial for its portrayal of female sexuality and figured in the development of second-wave feminism. The novel is written in the first person: narrated by its protagonist, Isadora Zelda White Stollerman Wing, a 29-year-old poet who has published two books of poetry. On a trip to Vienna with her second husband, Isadora decides to indulge her sexual fantasies with another man. Its tone may be considered conversational or informal. The story's American narrator is struggling to find her place in the world of academia, feminist scholarship, and in the literary world as a whole. The narrator is a female author of erotic poetry, which she publishes without fully realizing how much attention she will attract from both critics and writers of alarming fan letters. The book resonated with women who felt stuck in unfulfilled marriages, and it has sold more than 20 million copies worldwide.
