Review: When I picked up this book, I knew I had read it before, but I couldn't remember a single thing about it, as opposed to The Changeover, also by Mahy, about which I can remember much of the plot, but never the name of the book (although I suppose I've fixed that now, haven't I?). That I found this book completely forgettable the first time around, and not much better the second, probably tells you everything you need to know.
