From publisher blurb:
The Monster Mash Returns!
While for the mortals Halloween is the celebration of All Hallow’s Eve (i.e. the night before All Hollows’ Day also known as All Saints’ Day — at least by Christian reckoning), for the supernatural and other “things that go bump in the night,” it’s Samhain and by both ancient decree and powerful geas (i.e. magically-enacted Law) no monsters may “hunt” tonight.
As such, the various monsters in and around town — or at least those able to be under one roof at the same time without fighting — have gathered at one of the monsters' lairs (by default assume a vampire lord) to party and discuss plans for the coming year.
In past years, local Witches were allowed to attend, but last year there had been a breach in security and it’s believed that MORTALS had been at the party, so this year “monsters only” are invited.
But when have things like “rules” stopped teenagers from doing something stupid like crashing a party?
This Double-Page Adventure includes special rules that are enhanced by having Stranger Stuff: Teenage Witchcraft but the book is not needed to use this adventure. It also is specifically a followup to an Adventure Seed that was included in Stranger Stuff: Something Wicked but the book is not needed to use this adventure.
