Yay! Now you can read Uncharted: Story for a Shipwright on your Kindle reader. Download it from Amazon.com
As a side point, if you have not yet purchased an eReader of some sort and are considering it, and if you still like to support your local independent book store, many of them sell eBooks through their Websites.
If you choose to purchase a Kindle, you can only download books through Amazon, which does not benefit the independent book store. I love my Kindle, but that long-term implication never occurred to me; I would have purchased a Nook, iPad or one of the other fine eReaders available. Uncharted will soon be available for those devices also.
And of course, you can still read it in a lovely matte covered paperback--feels so good in hand!
