This a solid little Forgotten Realms scenario that offers a dungeon crawl and a mystery to be solved. The investigation is straightforward and almost cursory and the bulk of the scenario deals with the description of a reoccupied orc fortress. The occupants are varied and have sufficient backstory to keep things interesting. However there is an element of the set piece being frozen at a particular moment in time until the PCs roll up. There's no particular advice on how to use the centrepiece of the scenario in a campaign.
As you might expect from Wizards the production values are all very slick and all the crunchy stats are provided and can be used outside the booklet to provide orc groups capable of providing a challenge to a wide variety of groups.
The final analysis for me is that this is a pretty good example of a middle of the road D&D scenario. If you are looking for a conventional bash for a a few nights entertainment then you are going to be happy. I liked a lot of the ideas about having an orc stronghold and I think a lot of the material can be used outside the scenario but a lot is going to depend on how well you stomach D&D in the first place.
