I believe it wasn't part of the line, but it deals with the aftermath of the metaplot events that ended Wraith (which was one of my favourite games in concept, but I didn't like the execution). It was in essence Wraith with the perspective flipped to focus on the living rather than the dead, you worked for a corporation that dealt with hauntings and employed both psychics and ghosts, and I believe that later in the line you had to deal with other corporations dealing with the afterlife in a much less ethical fashion.
While I can't remember the names there was like two types of human (those who could astrally project on command ans those who needed to be frozen for it), normal ghosts, and a couple of kinds of special ghost. Changes from Wraith included Arcanoi being replaces with Horrors as ghostly abilities, and ghosts no longer having a Shadow in their heads but instead having an evil doppelgänger. Also Oblivion got changed, and I believe was focused on Grandmother rather than the Neverborn(? I forget if Wraith used Neverborn or Onceborn, or even both).
Now I'm trying to remember if Demon had any options other than demons. I don't think it did, both Hunter and Demon seem to have been more focused than the games which came before them.
