Greed and ambition threaten to tear the north apart.

War rages between the two kingdoms of Northumbria. Kin is pitted against kin and friend becomes foe as ambitious kings vie for supremacy.

When Beobrand travels south into East Angeln to rescue a friend, he unwittingly tilts the balance of power in the north, setting in motion events that will lead to a climactic confrontation between Oswiu of Bernicia and Oswine of Deira.

While the lord of Ubbanford is entangled in the clash of kings, his most trusted warrior, Cynan, finds himself on his own quest, called to the aid of someone he thought never to see again. Riding into the mountainous region of Rheged, Cynan faces implacable enemies who would do anything to further their own ends.

Forced to confront their pasts, and with death and betrayal at every turn, both Beobrand and Cynan have their loyalties tested to breaking point.

Who will survive the battle for a united Northumbria, and who will pay the ultimate price for lord and land?
