Uhtred the fearless and instinctive warrior, begins his voyage north to avenge Earl Ragnar’s death and recapture his ancestral lands of Bebbanburg from his traitorous uncle, Aelfric. King Alfred’s conviction to unite the separate kingdoms of England is stronger than ever and he sets his sights on the wild lands of the north, which have fallen into the control of savage Dane brothers Sigefrid and Erik. Upon receiving word from Brother Trew and Father Beocca about a prophesised new king in the form of Christian Dane Guthred, Alfred sends the priests on a rescue mission, weighted in silver to free Guthred from the hands of slave traders. Elsewhere, Uhtred still feels the loss of Iseult and, fearful that they are straying from their journey north, Hild takes matters into her own hands to advance their quest. While crossing paths with Father Beocca in Eoferwic, Uhtred finds himself embroiled in a rescue mission and is brought face to face with an enemy of old. As the team enter into dangerous territory, will the exchange of ransom go to plan?
