When I think about it, that's the one thing I hate about books. I get that they have (a lot more detail) but there's something maddening about a story you have to continually chip away at...rather than one you can just experience all at once. A book only really works as a whole unit, yet it inevitably must be consumed bit by bit. Only a serious reader can experience the whole thing at once, and rarely does an author give a "reading schedule" to control how long a reader should take to move through the story. It's a drip-drip-drip...especially when read in school.
Will my students finish the novel tonight? Who knows. Some probably will, but the rest will have to keep chipping away. Sadly, only by the time they're will they realize they should have read much faster all along.
