Isadora Wing turns something like 60ish

Isadora Wing is the funny, vivacious heroine of Erica Jong's memorable book, 

Isadora is in a perpetual state of unzipment, one could say.

Critics are celebrating the 40th anniversary of Fear. Jong writes an essay on it as well. 

A book like Fear would have only been possible in the 70s, an era described by Jong as "thrilling", producing both "startling wisdom" and "banal blather."

Fear has sold over 3 million copies worldwide and has been translated into 40 languages. 

Publishers wouldn't touch Jong's manuscript initially, but it got popular through word of mouth, much like E.L. James' Fifty Shades did, but without the aid of the Internet.
