Told in a rhyming format, Rainbow Rain tells the story of a rainbow who has fallen from the sky to protect herself from the rising fumes that are causing her to overheat and fade away. Rainbow Rain has a magical yet serious spin on the importance of protecting our planet from global warming. The story begins with Billy, a rainbow chaser, who becomes increasingly troubled by his missing rainbow and so turns to his friend, Meg, for answers. Meg's child-friendly explanation of global warming, pollution and recycling is accompanied by the dreamy and sometimes humorous illustrations of Laurie Heng.
