When the lights go out and the moon comes up, a little boy and his Gram take to the beach to play. One by one, they are joined by a cast of family characters who become part of a fanciful midnight adventure. But even pirates, a ghost, and a sea monster get sleepy when the mist comes in and Uncle Pat takes out his harmonica.M. C. Helldorfer's warm, lyrical story and Alexi Natchev's bright, playful art perfectly capture the magic and fun of a late-night romp on the beach.
