Another zany witch story from The new York Times bestselling author of Which Witch? A witch who wants to Do Good? In the world of Eva Ibbotson, this means trouble. Heckie, a graduate of one of the best witch schools, settles in the town of Wellbridge, determined to discover evildoers and turn them into... animals. She turns the mean owner of a nasty nursing home into a warthog, a bank robber into a mouse, and a cruel chicken farmer into a fish. The Wellbridge Zoo is pleased, but Heckie's do-gooding is about to land her and some of her young friends in big, hairy trouble.
