Jean Slaughter Doty is one of my favourite American authors, so I was pleased to see the Mokey books were going to be readily available. However, beware: the books have been republished as part of Random House's Stepping Stones series, so this doesn't mean you're going to be the original text. What you will get is nice, short sentences and simplified content.
Below are examples of how it's changed - thank you Susan Bourgeau for sending me this.
If you have a reluctant reader, then go ahead and buy, but if you're looking to recapture the magic of a book you read when you were young, hang out for a secondhand copy.
