I have adored several of Konigsburg's books, but this is not one of them. I remembered it fondly from my youth and picked it up at a Friends of the Library sale, but I found that it hasn't held up particularly well- at least to my eye. Jennifer is intriguing but never explained to my satisfaction. There is a paucity of any sort of description in the book- I was longing for more of a sense of place. The witchcraft training is fairly interesting, but the ending falls entirely flat and is unsatisfying in every single way.
