Like Loz, I generally don't get too excited about giant episode as they just tend to be a normal size story bloated to twice the normal size. But (also like Loz) I thought this one was really great, my favorite Podcastle in quite a while. I did have trouble keeping the demons' names straight, which probably would've been easier in text, but it didn't cause me any major problems.
I liked the way the rules of the world played out piece by piece, revealing the demons right away, then adding the powerful men of god, and the power of a Sending. Several good turns that took me off guard, from the apparent reveal of Squaw Bess as an angel, then the reverend's incorrect revelation that he is the Sending, and that the Sending actually worked in the Mountain King's favor, that was really great.
I haven't bought any books for quite a while, because my bookshelf is overflowing with the unread books the way it is, but I might have to make an exception for Hobson's book.
