Gioga is a gift from the sea to the childless Jannet and Munroe--but only a temporary one. The couple treat Gioga as if she were of their own flesh and blood, not understanding that they would need to let her go before long. When it comes time to return their daughter to her rightful home, desperation sets in. No amount of toil and bloodshed, however, will distract Gioga from the longing she feels to return. . . .
