Death decided that he needed a place to live, so Death's Domain was born, just nobody is exactly sure precisely where it is. "Death, significantly, does not see many crypts or coffins. Most peole die at home, or at sea, or at least out in the fresh air." So therefore there isn't anything terribly gothic or spooky about the house--except that everything is in various shades of the colour black.
In the tradition of previous Discworld Mapps this volume contains a large map and a booklet. I honestly found the booklet and the border illustrations the best.
I really like Kidby's illustrations of Death and his associates so that is quite enjoyable. Not only are we treated to Death, Susan, and Albert but we see Death of Rats peeking over an edge and his raven in the midst of black roses. And don't forget Binky!
The booklet was also quite illuminating, especially the discussions between Albert and Death concerning the golf course and the maze. The character of Death as portrayed by Pratchett has long fascinated me (it is nice to see him in every book) and it is fun to see more of him than before.
However, we don't actually see the inside of the house (since it is larger on the inside than the outside). Also, somewhat disappointingly some of the details were too small to properly make out. I would have really enjoyed seeing the tree swing that Death made for Susan, but it is far too small to see anything clearly.
Finally I would encourage casual fans to not pick up this volume unless they're really fascinated by Death. Yes it is interesting (and vital to the diehard fan), but it doesn't add too much to the books and doesn't make much sense just on its own.
