This memoir-cum-letters, poems and analytic interpretation (Jungian) has been prepared by Mr. McCurdy, who has studied other geniuses, and there is no question that Barbara qualifies from her exceptional beginnings to her unexplained end. She disappeared altogether after the breakup of her marriage. Barbara never went to school but she learned to type at five (it's reassuring to note she still had a stuffed rabbit at four), invented a whole Arcadian fantasy world, had a book published at thirteen (by Knopf-- well, her father was an editor there) and was obviously traumatized by her parents' divorce. This book consists chiefly of her work, sometimes written in the language she also made up. All in all, it's a curiosity-catching item which may, or may not, have real significance.
