This is one of those not-a-Mama-favorite books that Charlotte really likes. It is short, it involves children dressed as witches, and that's about all that Charlotte requires. It is a little bit cute, though, for all that I'm weary of it. The witches are twin girls named Emily and Ella, and you are given hints in the text to guess which witch is which in the pages. Charlotte does like guessing which witch is which, and the illustrations are lovely, so I put up with it. It is, after all, a library book.
