Isolde has fought monsters, gods, and her own past. But nothing has prepared her for this—a city on the edge of collapse, its people turning against each other, and a war that threatens to swallow them all.

The enemy she thought she had defeated is rising again, stronger than before. Aidan, a druid bound by fate, senses that the world itself is breaking. Jen, a hacker with nothing left to lose, uncovers a final, terrifying secret. And Cassius, a demon who has fought for centuries, knows this battle will decide more than just Valhaven's fate.

Because this isn't just a war. It's a reckoning.

The Morrígan's forces have thrown the city into chaos, and at the heart of it all stands an ancient terror—Stheno, a gorgon whose rage has burned for millennia. She doesn't just want power. She wants vengeance.

To stop her, Isolde and her allies must fight their way through a city on fire, into the depths of a conspiracy older than time. The truth they uncover will change everything.

If they fail, the streets will run red, and the world will kneel before a new queen of death.

The final battle for Valhaven has begun.
