The famously disaster-prone Mildred, witch in training, flies in for a brand-new adventure that makes a perfect Halloween treat. Mildred is starting her third year at Miss Cackle's Academy for Witches with high hopes of improving her klutzy record. But that's before a curling-iron catastrophe leads her to experiment with a hair-growing potion with hair-raising results. And it's before she raises the ire of Miss Granite, the odd new teacher who doesn't seem to act like a teacher at all. Could she be an imposter? And is there anything in Mildred's bag of tricks that can save the school if her hunch is right?Murphy, Jill is the author of 'Worst Witch Saves the Day ', published 2007 under ISBN 9780763633196 and ISBN 0763633194.
