It is 954 A.D. and a tempest is brewing in the North. Twenty summers before, Hakon Haraldsson wrested Norway's throne from his murderous brother, Erik Bloodaxe, but he failed to rid himself of Erik's family. Now the sons of Erik have come to reclaim Erik's realm and avenge the wrong done to their father and their kin. They do not come alone. With them marches an army of sword-Danes sent by the Danish King, Harald Bluetooth, whose desire to expand his realm is as powerful as the lust for vengeance that pulses in the veins of Erik's brood. Like storm-driven waves, the opposing forces collide in War King, the action-packed sequel to God's Hammer and Raven's Feast.
