Hmm.

Brian Selznick's The Invention of Hugo Cabret is a 500-plus-page-long picture book for older children--maybe 40% text and 60% images. I read and enjoyed this book, but I was a little taken aback by the price ($22.99--a whopping 6 bucks more than your average YA hardback) and a lot taken aback by the news that they've made an audiobook version. How, exactly, does one make a three-hour-long audio version of what is basically a graphic novel?
