Rupert Brown's pets, a pair of guinea pigs, a turtle, and a cockatiel, have started talking to him again, a sure sign that Miss Switch, a bona fide, no-fooling, real witch, is back again as Pepperdine Elementary School's enormously popular sixth-grade teacher! This can only spell one thing: the wicked Saturna has never forgiven Rupert for blowing up her judgmental Computowitch to save Miss Switch from its idiotic verdict. So back she is, this time contriving a plot that employs villains so vile they can only be imagined between the covers of actual books. With no Computowitch to help her, will Saturna devise a way to make sure that Rupert and his unlucky classmates meet the same terrible ends as these vile villains?!
