It's also available in paperback (for $10!). If you're serious about learning to write well, it's well worth putting down the Kindle and going "old school" on this one.
Yeah, I'm just not from the US so I don't like to wait for the package to arrive, pay extra for the shipping, then have it clear customs, etc. Kindle provides instant gratification and all that :-)
I'm not in the US either, but patience is a virtue, and good things come to those who wait. The Kindle is great, but don't let it form the limit of your world.
