This is, hands down, one of the best adventure paths out there. It is a combination of intrigue, dungeon delving, and hack-and-slash. The adventure is somewhat heavy on wizards (which I didn't mind) and a little bit of a meat-grinder, but very good overall. You may need to adjust the encounters some for a particularly large or powerful group but it is mostly balanced.
My group had a very fun time playing it and it is a excellent start for those wanting to get into pathfinder. It is good to see Paizo puts a lot of work into their products and that they are still excellent.
