This should be on any DM's shortlist for beginner adventures. A good mix of puzzles and combat. It moves along quickly and I ran the whole thing in 3 hours, skipping one optional encounter towards the end. Each of the encounters has a little something extra to make it interesting rather than just a straight fight. A little light on the roleplaying, but in my experience most new players need to ease into that so I think it's well-balanced. I would love to see more from this author.
