This book is so weird, and I'm having a difficult time wrapping my head around the fact that it was written by the same woman who wrote The Outsiders.
OK, so the parents in this story get a dog instead of a brother or a sister for the only child in the family, a boy. Fair enough. The book is told through the voice of the dog. Also fair enough. Then the dog decides that she really wants to be human, concentrates on that desire really hard, and slowly turns into a sister. Weird! Weird! Weird! This is definitely a companion book to Stuart Little (which, even as a child, I thought was a strange and impossible story).
I was ranting and raving about how improbable the central theme of this book is, and Tony pointed out that it must be a metaphor. Aha! I realized he was right. It's a metaphor for puberty (even though the dog sister is only about seven in human years when the change begins). She goes through a period when she is not quite a puppy and not yet a human...That is a very awkward time (especially since she has to stay hidden away from everyone besides the immediate family in fear that outsiders will freak out about a dog turning into to a human).
Kids would understand what the book is about, Tony said. I wonder if I would have understood if I had read this book when I was eight or ten. I don't know. I think I have always tended to think very literally. Oh sure, I can get into a book about magic and dragon and other totally impossible things, but a dog turning into a kid is just something so far out that I'm not really able to believe it, even just for the time it takes me to read a book.
