A really nice product for any novice GM that wants to enter the world of dungeon building and OSR games. An experienced GM would find a complete dungeon as a nice addition to their folder of adventures, albeit a somewhat linear experience at first.

Some things that I miss from the adventure and key for any OSR dungeon are a brief description of a base town/city, the surroundings of the dungeon and a table of rumors. The first two are on the hands of the GM, but the third could be easily made with some of the dungeon's "lessons".

I like to play one-shot adventures and I find that for players already familiar with DnD, starting at level 1 can be rather disappointing. This can be a nice adventure for a level 4 party if used for a quick session or it can be adapted for a larger storyline (more on this later). The story itself it's okay, making the characters take the call of adventure early, a clear objective and a villain to fight at the end. But some parts of the adventure might not work as well as the others, during the middle point of the story the party has to do a trip to the site of the adventure, this part is not that much fleshed out and you might want to do some changes. Also, in the final battle against the necromancer you might want to change her spell list so that she uses necromancy spells (she is mostly an evocker with large HP and invisibility). There are some typos here and there, but what really bugs me is that some encounters are obfuscated in the text, on it's even inside of a "read aloud box". This is not a problem, but something that can be improved for some ease of reading, and that would also include adding a page reference for some monsters. As I said before, you might want to change thisfor a longer session or two. You might want to make the trip to the site more perilous or you might want to change the ending. This can be a good story to introduce the Shadowfell early on, and forcing the party to travel inside the plane might be something unexpected to throw off your players. Or maybe you players fail to defeat the mage and it can turn to be a more horror themed story. Over all, I think it's a good product and you should give it a try.
