From publisher blurb:
Beware the darkness, for it is alive with the dead!
Now, the nights of Ravenloft are more horrifying than ever. You'll find out why in the pages within. Follow Dr. Rudolph Van Richten, Ravenloft's leading authority on the supernatural, as he reveals how to hunt the hosts that lurk in the blackest shadows of midnight. Van Richten tells all that he has discovered about the incorporeal undead; he explains their origins, the passions that draw them back from beyond the grave, and the horrible powers bestowed upon them in unlife.
For countless years, Van Richten has traveled the misty roads of Ravenloft on a mission to destroy the undead wherever they might be. Now, your characters can join him on his courageous quest. In addition, he offers his wise counsel on the ways in which there fiends can be stalked, confronted, and destroyed.
Be careful, for these ghosts are not simple, moaning spirits of darkest night. These are the ghosts of Ravenloft.
