I love everything that has to do with Drow, and this one was a nice surpise. The maps are very detailed and easy to use and the rest of the artwork is eye cathing as well. The npcs provided are interesting but i intend to change them to suit my campaign, although i might 'borrow' an idea or two. The house is placed in Menzoberranzan but you can easily placed it in any underground city that you like.
All in all a well made book with lots of details in the maps and the description that comes with them. A purchase that you wont regret if you like dark elves.
