Shadows of Midnight has published three adventure locations, and I recommend them because of their links to The Unexplained (Carnivore Games, http://carnivoregames.com/wp/).

"Mary's Tower" (36 pages) is totally systemless and focues on a location and its surroundings, provinding the same detailed descriptions of paranormal and non-paranormal research done along with photographs.

The text is farily easy to read (except for the introduction which is a little blurry) and the printing is quick for most of the documents (some slight delay for the heavier colors).

I recommend them.
