It's time for Grayling to be a hero. Her mother, a “wise woman” -- a sort of witch -- has been turned into a tree by evil forces. Tangles and toadstools! Lacking confidence after years of being called “Feeble Wits” by her mother, Grayling heads off dubiously into the wilds in search of help, where she finds a weather witch, an aromatic enchantress, a cheese soothsayer, a slyly foolish apprentice, and a shape-shifting mouse named Pook! A fast-paced and funny coming-of-age odyssey from a Newbery medalist.
