"Every year, Yuka led us from the warm Caribbean Sea where we spend the winter all to way to our summer feeding grounds among Arctic icebergs."

But this year Yuka feels herself too old to lead the pod. She will stay behind and a new leader will guide them. Young Uki is worried. She can't imagine anyone replacing wise Yuka. But when the pod's bold new leader is trapped in a discarded fishing net, Uki finds she has the courage and vision both to rescue him and guide them all safely to the distant Arctic.

In this imaginative and beautifully illustrated story, the annual journey of a pod of humpback whales from the Caribbean Sea to the Arctic Ocean is traced with informative detail and luminous images of their undersea world.
