I didn't know it was part 2.
It wasn't so much confusion that put me out as the way the story was being told. So, I'm trying again from part 1. :P
Found a really nice deal on B&N. $10 for an ebook of the three parts, plus maps and other supplemental material. The print edition from the same publisher is $52.
So, $10 + tax later, I had me a big ebook. Yay.
It's $9 on Amazon for the same thing, but I use a Nook 1st edition. I don't mind paying a little bit more to help my favorite brick-and-mortar store.
