Valhalla's Fury

Ribe is lost, its hall burnt, and Charles is still missing. Sven must once more sail into dangerous waters to rescue his grandson.
King Louis of East Francia, the man who took Sven’s son from him almost twenty years ago, has Charles captive and uses him to force Sven to do his bidding and create chaos raiding his brothers Kingdom of West Frankia.
The long awaited meeting of Charles and his mother, Abbess Hildegard, is not what Charles dreamed it would be and soon it becomes clear that Charles is in even more danger. Torn between the heathen gods and his Christian god, Charles must decide where his future lies.
Sven must fight if he wants to see Charles again and keep the Cross of Charlemagne out of the hands of the Frankish kings. The only thing that Sven knows is that to save Charles, innocent people must die.
