A little boy with pirates on the brain navigates the first day of school. Narrating in a vigorous piratespeak, he takes readers through his day. “Then in the galley, I mashed me choppers on grub and drowned it with grog.” It may come as no surprise to learn that school comes as a bit of a letdown: “ ’Twas good enough for lubbers, I suppose. But where’s me treasure?’ ” he asks his teacher, “Cap’n” Silver, at the end of the day, and she obliges. Ruth matches the narration with striking line-and-watercolor graphics, surrounding his hero (who sports a skull-and-bones athletic jersey) with sepia-and-white pencil renderings of pirates (and a parrot) who silently kibitz on his day. Pirate-addled readers will dance a jig; press-ganged kids will be happy for the glossary. Good fun, me hearties. (Picture book. 4-7)
