When Dizzy was little, her mother went away - traveling the festival circuit. But every year she sends Dizzy a birthday card. This year it's different: she shows up and offers to take Dizzy on the road with her, traveling from one festival to another. But Dizzy discovers that things are not always as wonderful as she had hoped. And that her mother is not quite as wonderful as she seemed.
A rather predictable story of how our dreams/wishes don't get realized in fact as much as we imagined. There is a major lack of plausibility to Dizzy's easy acceptance of her mother's lies - lies that probably every reader is going to figure out without the help. Passable, but ultimately unfulfilling.
