MARK Z. DANIELEWSKI is the author of some pretty complicated books. The Little Blue Kite, though, is pretty simple. And, sure, maybe there is more here than just big beautiful skies, but who are we to start babbling about the virtues of letting go, especially in a bio, which is really where we should just say the author lives in California with his wife, daughter, and two cats, Archimedes and Meifumado, all of whom know that the wonderful thing about flying a kite is that in the end you don't even need a kite.
