Saturn has fallen, magic is unraveling, and Robin stands at the heart of the ruin—with blood on her hands and betrayal in her bones. Traded like a weapon by the person she trusted most, Robin now finds herself in the clutches of High Chancellor Aiden—the man behind the fire, the conqueror cloaked in charm and cruelty.
He’s come for the final Celestial Key, the last piece of ancient power that will seal his dominion over the shattered Houses. And Robin? She’s the only one standing in his way.
But how do you stop a tyrant when everyone you love is gone?
With danger closing in and secrets rising from the ashes, Robin must decide if she's willing to become the monster to defeat one—or if the spark of hope still flickering in her chest is enough to reignite the world.
