Why you need to re-read Catcher in the Rye...

...so that then you can read My Salinger Year by Joanna Rakoff with authority.

"Poignant, keenly observed, and irresistibly funny: a memoir about literary New York in the late nineties, a pre-digital world on the cusp of vanishing, where a young woman finds herself entangled with one of the last great figures of the century." (from GoodReads)

And yes, that great figure is J.D. Salinger.
