I ran the adventure, "Throne of Bone," found in this collection last June. It was simply fantastic in every way. My players enjoyed the Gruff Dwarf door and all of the thought provoking challenges along the way. I used Jeff's adventure as my base, and then changed or adapted the game to my style of play. I found that all of Jeff's notes, suggestions, and maps were a huge help. I would highly recommend this product to any DM.
