I ran my players through this one after Hollow's Last Hope. We had a great time returning to the Dwarven Monastery and delving into the dungeon beneath it.
The only reason I don't give it 5 stars is due to some typos in the stat blocks. One in particular to watch out for is the Forge Spurned's damage. IIRC, it is listed as 2d4+10 with its chain. It should read 2d4+1. That particular typo TPK'd my group and brought the adventure to an unceremonious end.
Still, we loved the adventure up to that point and I'm sure we would have had a great time beyond it as well. And even when the players had been slaughtered they still said they had a good time.
One thing that may bug people is the children in the dungeon. If your group takes a long time getting to them, their survival becomes a bit suspect and you may need to address that. Some of the rooms come off too obvious as moments suspended in time that only activate when player characters enter the area.
That's a necessary evil in most RPG design, but be aware that it's there and you may need to tweak it just a tad so you don't have to push your players' suspension of disbelief too far.
Overall, great module and one I'd recommend to any group starting off. The kind of stuff I've come to expect from the Young Master. :)
