Five have a Wonderful Time

I'm not sure why this book is called what it is. I thought all the children were going to have an excellent time, and in some ways I guess they did.
It was good to see Jo in this book, and while she's got her same spunk, she and George got along a bit better in this book.
I didn't really see the twist at the end of this book, but it was sort of surprising for a Famous Five book. :)
