Heroic legend Beowulf returns to his childhood home of Herot to pay his respects to ailing ward and Thane of Herot, Hrothgar. However, his gesture of goodwill soon opens old wounds. With its defences fast fading, Herot falls under attack from within. Beowulf vows to remain until the enemy is routed out, justice is served and Herot is safe once more.

Herot is bustling as the town makes preparations for the Gathering at which the next Jarl, leader of the Shieldlands, will be elected. With the other tribal leaders due to arrive in Herot at any moment however, the pressure mounts to catch Herot’s killer before another victim is claimed. In a bid to buy themselves more time and avoid panic amongst the tribe leaders, Rheda, Slean and Abrecan ride out to stall them whilst Beowulf begins his search.

With Slean and Thane Scorann missing, Beowulf and Rate, Thane of the Varni, ride out into the forest in search of them. But with the Gathering fast approaching and Rheda’s bid for leadership depending on the hope of ever-loyal Scorann’s vote, Beowulf questions whether their disappearance might be more than a simple coincidence.

As Herot is preparing for Slean and Keta's wedding, shocking secrets are revealed and the couple must decide if new loyalties are to be forged or irrevocably shattered. Meanwhile, with Rheda’s new laws permeating the tribes, Abrecan is forced to choose between stepping aside and accepting his sister's rule or standing against her in a declaration of war.

The battle of all battles falls upon the peoples of Herot. Weapons forged, loyal and armed, men, women and children brace themselves to wage a brutal attack with Beowulf helming their defence.
