by Holly Black and Tony DiTerlizzi (2003).
Super-fast but fun little read. The illustrations really made this book for me--reminded me of old Nancy Drew volumes (where the pictures have a quote from the text and then you read the chapter, wondering when you'll get to that sentence).
I wonder how many of the five books the movie will cover. The first book could be done very quickly onscreen, but who knows how it'll actually play out. Anyway, I'm excited to read more.
