In the battle for power, there can be only one ruler.
Athelstan is the king of the English, uniting the petty kingdoms of Wessex, Mercia, the Danish-held Five Boroughs and York following the sudden death of his father, King Edward.
His vision is to unite the realms of the Scots and the Welsh in a peace accord that will protect their borders from the marauding threat of the Norse Vikings.
Whilst seemingly craving peace and demanding loyalty with an imperium over every kingdom, Athelstan could dream of a much bigger prize.
But danger and betrayal surround his best intentions, namely from his overlooked stepbrother, Edwin, who conspires and vies for what he deems is his rightful place as England's king.
As ever, powerful men who wish to rule do not wish to be ruled, and Constantin of the Scots, Owain of Strathclyde, and Ealdred of Bamburgh plot their revenge against the upstart English king, using any means necessary.
An epic story of kingsmanship that will set in motion the pivotal, bloody Battle of Brunanburh where allies have to be chosen wisely...
