I got it at GenCon, authors and contributors have their copies. Have you considered ordering straight from them?
Besides, I don't know what your expectations are, but I have found it to be mediocre. There was so much I was hoping they would do with this, and they did nothing but turn this into a 20 level dungeon crawl with no real reason to go into it other than level up and gain treasure.
I was very dissappointed. There was so much they could have done! :\
