It is Constantinople in 1035, and Thorgils has become a member of the Varangian lifeguard, where he witnesses the glories of the richest city on earth. He embarks on a campaign launched to recover Sicily from the Saracens. After years of traveling, Thorgils retreats to Sweden, but is eventually summoned again to assist in coordinating William the Conqueror?s invasion of England. In September 1066, a Norse fleet of three hundred ships sails towards England and the battle begins. It is a prophetic dream that makes Thorgils warn the troops of the impending disaster at Stamford Bridge, but even he cannot turn aside what fate has decreed?the end of the Viking world.
