After narrowly escaping the sinister plotting of Anthony Arlen's City Guard and the wrath of the outlawed Sun League, Kit Porter and his friends, Alec Weston and Robert Warren, must flee or risk capture—or worse. With enemies dogging their every move, the friends risk a brief, heartbreaking meeting with Kit's mother before pushing on to the town of Ludlow. There, they enlist the aid of Jamie McEwen, a rich merchant and old friend of Alec's, who offers them a way out. But in order to make good their escape, they must first reach Boston, a port city on the other side of the country.
