This is an enjoyable story told in the style of fairytales, however I have read it a couple of times now and still don't find it very memoerable. It is simply a nice, cheerful tale for younger children.
"Over the wide world they flew. Far below, tiny people ran to catch flying hats; ships like toys ran before the wind with bare masts. The North Wind laughed and Onda thrilled: Onda, wind rider. Onda is a sprite, a spirit of the air. She can go where she pleases and do as she likes. But, like all spirits, she has a special task to perform. First she must fly to the Land of the Four Winds, to the Yellow Kingdom and the Red Kingdom. There she must try to unravel the tangled relationships of four humans - a prince, a princess, a ploughman and a milkmaid - and bring them all to happiness. Only if she succeeds, will Onda herself be able to find true happiness."
