When Felicity (aka "Flissy") Bathburn's parents first dropped her off in Bottlebay, Maine, she hated everything about it. She hated the big gloomy house she was to live in. She hated meeting her long-lost and highly eccentric relatives. And most of all, she hated knowing that she was safe in America while her parents faced the guns of WWII in Europe. But a year has passed now, and Flissy has grown to love her life in Bottlebay — and especially Derek, the boy the Bathburns have adopted. Then a man claiming to be Derek's true father arrives, and soon he's asking all sorts of strange questions. Flissy has a nose for trouble. Has Derek's new father come to take him away...or is there something even more sinister happening in Bottlebay, Maine?
