I thought I knew Baba Yaga. I was wrong. Baba Yaga, in Gregory Maguire’s Egg and Spoon, has sass and wit! You’ve got to meet her! Here’s the pith of the plot: Spoiled rich girl, honorable peasant girl, and a misunderstood Russian royal join forces to save the world. Why is the world in trouble? Eggs! The accidental switch of two eggs (a priceless, if tasteless Faberge, and the priceless, immortal Firebird) It’s funny, mysterious and archetypal. grownups (that’s me) will gobble it up.
