Halloween is just around the corner and Katharine Carmichael has made a spooky discovery! Her baby brother, Jack, is a monster—and not just any monster, he's Jackula, a blood-sucking vampire! On top of that, Crockett's endless Halloween jokes are driving her batty, she's sent to the principal for being a Stealie Girl, and she still doesn't have a costume. Will Miss Priss-A-Poo help Katharine discover the truth about Jackula before it's too late or will monsters take over Liberty Corner School's Halloween parade?
