Styrbiorn the Strong tells the grand tale of Styrbiorn Olafsson, heir to the Swedish throne and known both for his impressive size and strength and his unruly, quarrelsome nature. Denied his birthright and exiled from Sweden, Styrbiorn becomes the leader of the Jomsvikings and sets out to reclaim the Swedish throne in the epic Battle of Fýrisvellir. A rediscovered classic, Styrbiorn the Strong is a tale reminiscent of the Old Norse sagas, a historical novel from one of the twentieth century's most influential masters of fantasy.
