A boy and a bear go to sea, equipped with a suitcase, a comic book, and a ukulele. The bear assures the boy that their journey really shouldn’t take very long. But then they encounter “unforeseeable anomalies”: turbulent stormy seas! a terrifying sea monster! and the rank remains of The Very Last Sandwich.
Will the Harriet, their trusted vessel, withstand the violent lashings of the salty waves? And will anyone ever answer their message in a bottle?
