Continuing his line of teen-age novels on American history, (last year's: Winter of the Whale) Robert Carse here concentrates on the sea warfare waged by Maine Indians against British colonists during the late 17th century. By 1678, Indian tribes, once at war with each other, are driven by British maltreatment into an alliance against their common enemy. Their plan is to steal or destroy the sailing vessels on which the white settlers depend for winter supplies, leaving the colonists vulnerable to a final Indian massacre. During the bitter campaign, 16-year-old Massatuk and his cousin, both Penobscot warriors, form a gradual friendship with two Englishmen from the nearest village -- which friendship eventually leads the entire Penobscot tribe to declare for peace. By this time, however, enough British troops and warships have arrived from New York to wipe out all local tribes, hostile and friendly alike; and the Penobscots realize their only chance for survival is to flee north to Canada, leaving forever their beloved woodlands of Maine. A stirring and stingingly realistic illumination of a little known chapter of Americana.
