Eleven-year-old Jack Putnam and his eight-year-old brother Benny are being dragged against their will on a summer-long vacation with their family. And not to somewhere cool like Disney World, but to a little port town in Maine named Chowder Bay, far away from anyplace fun. But what promises to be a very bleak summer quickly becomes a series of exciting adventures in one of the most mysterious places on earth! This second volume finds the boys scaling a nearby mountain to confront a giant kleptomaniac eagle with an obsession with fancy hats!.
