When a weak king rules a rich land then the people suffer. When a power-mad ruler wishes to take that land then there is only one outcome. Sven Saxon Sword is content with his life but King Sweyn Forkbeard wants to use the Dragon Sword to help him claim a kingdom across the seas from Denmark. With Prince Cnut at his side, Sven has to fight not only the English but also Danes who change sides, Scots keen to grab land themselves and even the oathsworn of the new Danish king.
