Seriously, you guys, this made me want to become an astronaut.
There are various discussions on book trailers on various lists. Do they work, don't they, what are the components of a good book trailer, are they even worth the time. I like this one, although not having read Kitty, Kitty yet (sob!) I can't say yet whether it has much to do with the book in question.
ETA: because I'm a dork and didn't notice that the HTML for the videos was strangely truncated.
