Amazon.com description: Product Description: Steve Simmons and Cyd Moore's hit picture book Alice and Greta introduced two witches with very different views of the world: Alice, who uses her magic to help others, and Greta, who is always conjuring up trouble. In Greta's Revenge, Alice has foiled one of Greta's nasty schemes -- and Greta wants to get even. She casts a spell that makes Alice do mean things. But Greta has forgotten the most important lesson of witch school, the Brewmerang Principle: "Whatever you chant, whatever you brew, sooner or later it comes back to you!" Soon Greta is doing nice things for people. Luckily for both witches, the spell wears off -- but not before Greta has learned a little bit about the value of kindness. Ebullient illustrations perfectly capture the spirit of this clever, accessible, and satisfying tale that's eminently suited for Halloween -- and beyond.
