Nothing really. Which I found remarkable.
I'd never read The Devil Wears Prada (Lauren Weisberger) or seen the film, but plenty of my girlfriends have loved it, so when I saw the audiobook at the library, I picked it up. Rachel Leigh Cook did a fabulous job narrating and I was completely immersed in the story when Disk 1 ended and I reached for Disk 2, which turned out to be the real Disk 1.
Had I really just jumped into a novel partway through and not noticed?
Yes. Thank you, library patron who borrowed this audiobook before me.
I struggled with how to handle it. Put in Disk 1 and catch up on what I'd missed in the opening chapters? Or stay in the flow and go forward with Disk 3?
I went on to Disk 3.
The remainder of the book was as entertaining as I'd hoped and I had no trouble following along. When it ended, I went back and played Disk 1, finding that it didn't reveal anything I should have known to enjoy the rest of the story. The mistake actually reminded me of something I often hear in writing circles, which is that many of us open the action in our novels too soon. In fact, with Dead Lift, one of my critique partners told me to open the book with Chapter 4. That is the scene that now appears as Chapter 1 in the published copy.
My audiobook gaffe was amusing. I learned two things: Read the labels on audiobooks. And I want to rent this movie. :)
