Book excerpt: In this delightful picture book, Minnow seems to be the only one of King Neptune's fifty mermaid daughters who has no particular skill or accomplishments. That is, except for her persistence in asking many, many questions. But one day, as Minnow is drifting in the ocean all alone, a single red woman's shoe floats toward her seemingly from out of nowhere. Never having seen a shoe before, Willow becomes intrigued by what it might be. When no one in the kingdom can tell her, she sets off on a quest to find out and, along the way, uncovers answers to many of the things that have been vexing her, including what her true purpose is!
