The Valhalla Saga

A deadly war is coming to Stenvik - and in the clash between old and new, only the strongest will survive. The Valhalla Saga, Snorri Kristjansson's epic historical fantasy series, is perfect for fans of Vikings and The Last Kingdom. As punishment for disgracing his father, Ulfar Thormodsson has spent two bitterly uncomfortable years on the road, tasked with taking his highborn cousin Geiri on a tour of the kingdom.
Now his journey is almost at an end - the walled town of Stenvik will be their final stop. But Stenvik will soon become the battleground in a deadly war between the old gods and the new: King Olav is bringing the White Christ to the masses at point of sword and edge of blade, while a Viking horde led by a mysterious woman is sailing from the north. And Ulfar is about to learn that not all enemies are outside the walls .
