This is the first adventure we played back from 4th ed., and we had a blast!
Nicely packaged, with both GM and players maps, a nice array of handouts, well-documented appendixes that make life easy for the GM, the booklet in itself is of great quality. Since it is a .pdf format and production costs aren't implied, I would have liked a bit more color inside the booklet, but that's me!
The adventure has a lot to offer and should please to all styles of players and GM: part «sandbox», part dungeon crawl, the GM can choose to lead his players to certain parts of the adventure or leave them «in the wild» and let them run the pace of things.
Deep characters that aren't clearcut good or evil make it challenging for players to side with or go against some of the main protagonists, which I thought was good to keep them a bit off-balance.
Encounters are well planned, and easy to upscale or downscale if need be.
A word of caution: this might not be an adventure suited for beginning GMs: its loose ends and «sandbox» format might be rough to handle for inexperienced game masters.
