From publisher blurb:
After the horrors of SideQuests: Carnival of Terror, the players may have thought that the nightmare was all over... However, the terror is just beginning as the dark carnival has appeared once again! This spiritual sequel to SideQuest Vol.2's Carnival of Terror can be played as a completely standalone oneshot module, as a direct continuation of the events of that adventure, or even to be used as an expansion of the events of the original Carnival of Terror adventure. Featuring brand new attractions, even more harrowing puzzles, and a brand new cast of mysterious characters to populate the grim circus, players will have to bring their wits about them in this terrifying adventure module - or be trapped forever in the Festival of Fright!
