The cover has been updated, and I fixed a couple of late-found errors (during the proofing of the upcoming print version, I spotted some things earlier readers had not spotted). I also updated the blurb in preparation for a Pixel of Ink run later, as well as hopes that a longer blurb might grab Prime readers' interest.
I am moderating comments here, so if you find an error that you just have to tell me about, you can put it in the "comments" and I will see it (I have "release" powers on those, so I see them and have to approve them before they go public). This is a learning process, of course, and I'm finding that updates to the book are fairly easy. Once all of the initial readers' concerns are dealt with, I can actually update the entire thing, contact Amazon, and they will notify you, dear reader, that you can get a free updated version through the "Manage My Kindle" feature on your account.
