Sigyn, a siren now living on land, has found bliss in her blossoming relationship with the Norse trickster god Loki, however their pairing has caught the murderous gaze of Odin himself. Now she's marked for death by the All-father, just like Loki's tragic first wife before her.

On the run through ancient Greece, a close-call with Zeus threatens the couple's peace again, and Sigyn realizes she will never know peace while power-drunk patron gods tyrannize the earth.

So, when a powerful old acquaintance offers her a brutal solution, Sigyn takes it. She will end Zeus' reign of terror on women – and turn her eyes on Odin's Asgardian throne next. With Loki at her side, Sigyn will reshape the world for their love - or die trying.
