Loki, former God of Chaos, thought becoming mortal was his biggest challenge. He was wrong. When Frigg unleashes a devastating curse upon the gods of Asgard, Loki is imprisoned in the depths of Hel and the Nine Worlds are plunged into chaos.

The key to breaking the curse lies in a dangerous incantation-one that only Sigyn can translate. But finding her may be harder than escaping Hel itself. And even if they do, there's something about Sigyn that's changed, something that could doom their chances entirely.

Trapped without his powers, Loki's exiled children may be his only hope to save Asgard. As memories of pain and betrayal rise to the surface, past choices may work against him. Not to mention the wicked surprise Frigg has up her sleeve.

Curses need breaking, tensions keep flaring, and risks are even more dire than they realized as Jotenheim-Asgard's fiercest enemy-sees their chance to seize power and rule the worlds instead.

Loki is desperate for a plan, even if he loses everything, including his life-however, once a trickster, always a trickster, even if mortal. But the biggest trick of all might come from a god no one ever expected.
