This module plays as well as it reads. And that's a good thing because reading it was a real treat.
The Shoanti are one of the most interesting cultures in the Pathfinder setting. And what's really great is that this module "shows" the players what they're all about through direct experience rather than "telling" them through dry exposition. The quests are varied and highly imaginative too. My players enjoyed playing as much as I enjoyed running it.
So far, this is my favorite installment of the AP series. And that's really saying something because it's got some pretty stiff competition.
