The American Civil War may have ended but the tragic loss of one of the Ryan boys still holds heavy in the hearts of his family. Little Cece, born after her big brothers went to war, is a wise and knowing child who adds just the bit of glue her family needs to bind them during the hustle and bustle of rapid growth along the Penobscot River in Maine where bigotry towards native Americans continues to run just beneath the surface of everyday life. Twins, new immigrants from London, bring surprises that turn the static life at Prospect Ferry into unexpected mayhem. Romance, jealousy, brutality, fears, joy and despair mix to affect the family from Fort Knox to Indian Island to Aroostook County. If one dared ask, "What's next?" Cece would reply, "I not know." The final installment in the "Maine at Heart" trilogy, Beneath Mackerel Skies picks up where Granite Hearts left off and circles back to Smytheville where the story began with The Spruce Gum Box. An epic tale, the series spans several generations and decades of life along the rustic and emerging historic coastline of Maine.
