When we want a book exactly like the one we just finished reading, what we really want is to recreate that pleasurable experience--the headlong rush to the last page, the falling into a character's life, the deeper understanding we've gotten of a place or a time, or the feeling of reading words that are put together in a way that causes us to look at the world differently. We need to start thinking about what it is about a book that draws us in, rather than what the book is about.
