It is the 1570's, and the people of the Netherlands live in terror under the cruel dominion of Spain. Though many long to be free of Spanish tyranny, efforts at rebellion are failing, and allies are nowhere to be found. Edward "Ned" Martin, son of an English captain and a Dutch lady, is thrust into the conflict when he resolves to help his mother's people and avenge his murdered relatives. Entering the service of the revolutionary leader William the Silent, Prince of Orange, Ned is called upon to carry out dangerous secret missions deep within occupied territory. Through hairbreadth escapes, fierce sea fights, terrifying sieges, and daring rescues, Ned becomes a witness to the inspiring and heartbreaking events of the rise of the Dutch republic.
