When Draculaura and her ghoulfriends learn about human holidays, they can't wait to create the very first monster howliday! And since family is an important part of every holiday, the ghouls enlist their whole families-and one fangastic little vampire princess named Fangelica Van Bat-to help pull it all together. With the monstrous celebration just three days away, will Draculaura, Frankie Stein, Clawdeen Wolf, and all their ghoulfriends be able to think up the most creeperific howliday ever?
