Eilin, daughter of a Jarl, loses her father and brother on her wedding day and escapes into the sea. Rescued by Kaelan, a merman prince, she is given the Sea-Iron Axe — a key to a lost civilization tied to the World Tree. She joins the legendary Viking leader Ragnar’s fleet, raiding Paris, Rome, and Constantinople, chasing the Ragnvald family across the known world. Her cross-species love with Kaelan is tested by greed and conspiracy. In the end, she sails across the Atlantic to America — the new world born after Ragnarök. The axe still drips. Revenge is not over.
