Elara is a hunted woman. Born with the forbidden gift of fire magic, she lives a life of constant fear in the kingdom of Aethelgard, where the fanatical Order of the Ashen Gaze executes mages on sight. Her precarious existence is shattered when she becomes the target of the Obsidian Hand, a clandestine group of assassins whose resources and ruthlessness point to a powerful, unknown patron.

After a near-fatal attack, a wounded and desperate Elara crosses paths with Seraphina, a disgraced former captain of the Royal Guard now living as a sellsword. Bound by a fragile contract, the two women begin a perilous journey to unmask the person who wants Elara dead. Their quest leads them from shadowy urban underworlds to the peaks of forgotten mountains, where they must confront not only deadly assassins but the secrets of their own pasts.

As they piece together the clues, they uncover a sprawling conspiracy that threatens to destabilize the entire kingdom, orchestrated by a man who stands next to the throne itself. To survive, Elara must learn to master the power she has always feared, and Seraphina must confront the betrayal that cost her everything. In a world that wants to see them both destroyed, they discover that their greatest strength-and their only hope-lies in each other.
