Strange parallels

I'm obsessing over Julie Powell! Yesterday I finished her new novel, Cleaving. It was strange to read my feelings and almost identical situations from my life written by someone else in a novel about someone else. I am really tempted to google stalk her until I find an email address, and then send her creepy e-fan mail expressing my feelings of parallelism with her life and mine. I'm sure she gets it 300 times a day. I wonder though, how much of her work is autobiographical?
