I'm trying to gather a list of places selling the new book in order to make it ludicrously easy for people to buy it. Ha! It's shameless but I will add listings here as I find them (and welcome any and all suggestions).
I was inordinately pleased to find the book up at Buy Olympia - partly because you are always in such nice company there and partly because they do such a great job of presentation. (Also they do ship world wide.)
One of my other very favourite bookstores in all the world is Kidsbooks in Vancouver. I had a lovely visit with them when I was last there and am very happy to see them stocking the new book as well.
* And bless the bookbuyers as well! The comment from anonymous (below) made my day!
