Judy Blume is one of the most prolific and beloved writers of our time — but also is at the center of many debates over what is appropriate for children, to the point of being one of the most banned. Rachelle Bergstein, author of the new book The Genius of Judy: How Judy Blume Rewrote Childhood for All of Us, joins us to talk about Blume's life, how the changing social and political ideologies of the 1950's, 60's, and 70's influenced her work, and how Judy came to write 'culture-altering' works for generations of readers.
