I enjoyed the stories in this little book. They were very simply written, but touching all the same. And aren't fairy-tales supposed to be simply written? Since they are allegorical, if they are too complicated, then readers will miss the point.
Case in point: The tale about the Fountain of Luck. I felt that it was similar to The Wizard of Oz, in that what they most sought after was within themselves from the start, they just didn't know it.
Simple, fun, and heck, it's JK Rowling. ;)
