Just finished running this with my group and I must say it was AMAZING. Not only is the book crammed full of an amazing campaign that will befuddle and terrify players, but it is also laid out well that running this complex adventure isn't more ardous than any other linear story. Even if you're not sure if you're going to run this, I urge you to get this book, it's an excellent read through and can provide ideas for many other adventures.
