One of the great books of American literature, The Catcher in the Rye defies classification. You'll have to read it for yourself if you haven't already. Published 60 years ago, it is still among the most challenged books in schools and libraries.
I just read it again, for the library's adult book club discussions. At the first discussion last night, it was interesting to see how everyone referred to the book's narrator as if he was a real person. Holden Caulfield gets inside your head. I highly recommend The Catcher in the Rye.
