This was a nice bonus to the SKT module. I've been building up the relationship with Felgolos and the party for later in the module. This worked great. The module is well done and I don't remember seeing any spelling or grammatical errors. You do have to make this module yours since it is a hard balance between tension and TPK. The only thing I would have liked more would have been a better decription of the lairs. The module covered all the nuts and bolts of the ways to get in and stuff. However since they are two distinct lairs at times I was at a loss as to how they looked. In no was a deal breaker. Definitely worth the money.
