Clouds and rain and rainbows come and go. Two caterpillars watch, and travel through the pages. In the end, they become butterflies. Their adventure illustrates Joni Mitchell's famous song about clouds--and about life. Internationally acclaimed singer/songwriter Joni Mitchell evokes a sense of childlike wonder with the words of her classic song "Both Sides Now": "I've looked at clouds from both sides now, from up and down, and still somehow..." Alan Baker's delightful illustrations transform her words into the beguiling tale of two caterpillars about to become butterflies. This metamorphosis fascinates children and gains new beauty through this very special collaboration.
