I’ve written a review of J. K. Rowling’s book of fairy tales, Tales of Beedle the Bard Expands Rowling’s Moral Themes.
My least favorite story is “The Wizard and the Hopping Pot,” because it mixes themes and develops them poorly. My favorite is “The Fountain of Fair Fortune.” I find the other three tales to have interesting things to say about psychology, politics, and dealing with death.
