I downloaded it right away because I've become a fan of the series too. I was looking forward to making the switch to reading on my new NOOKcolor with this release.
Did you have any issues with the formatting? There's no indenting or double-spacing to indicate new paragraphs! They do start on new lines but don't stand out any other way, and I find that frustrating. I tried all the formatting/font adjustments I could find and didn't make anything better.
I wrote customer service and was told they "forwarded your feedback to the individuals responsible for NOOKbooks for correction." I'm still new enough to not know if there's anything else I can/should do....
