Unlike the first two reviewers, I have read it and prepped to run it.
The art is fantastic. The Adventurer's Toolbox has some exceptional pieces in particular. The maps, though a little small, are intricate and well-crafted.
Part 2 makes a lot more sense if you read further and rant less. Interesting terrain, creatures, and motivations all stood out.
If you enjoyed the (fantastic) 1E module, "The Harrowing," wait until you see what an even darker influence does to your favorite storykin.
It all ends in a brutal, epic showdown where the PCs prior decisions probably determine the outcome. Fantastic book to what's shaping up to be a potentially Golarion-altering story. Can't wait to start it!
