Pandora, Seabold, Whistler, Lila, and Tiny have all been enjoying the love and comfort that being a family brings. It is a comfort they are unexpectedly reminded of when Whistler and Lila hear the cries of a lonely baby beluga whale named Sebastian. When they learn that he has lost his mama, the Lighthouse Family, with the help of a cranky but noble old cormorant named Huck, does all it can to reunite mother and child.

Newbery Medalist Cynthia Rylant and illustrator Preston McDaniels invite readers to brave the elements once again, with a story that reminds us all about the strength and courage of family and friends.
