I'm going to cross-post this to the Mansions, Moonlight, and Madness discussion group.
I've created a shelf in my collection just for Gothics (and anything related) to make it easier for me and for anyone else looking for suggestions, since BookLikes doesn't have a separate category for them.
After finding the box of old gothics in the workshop, I realized there are others that I'm missing, books that I know I had at one time but can't seem to locate now. There are at least a dozen other boxes out there, some labelled and some not. It's almost as scary as a haunted house, but the horror is finding a bunch more cool books!
