A Throne of Ash and Teeth

"Do you still believe monsters should be saved?"Isolde Varrow commands the dead with grave-dirt on her hands and patience sharp enough to cut bone. Thessaly Ondrik burns heretics for a faith she no longer believes in, wearing obedience like armor and violence like a second skin. They should be enemies: a necromancer dragged before the court in chains, and the inquisitor ordered to escort her into a living labyrinth built to purify the wicked.
But the labyrinth does not want repentance. Its walls shift with hunger. Its traps feed on memory, blood, and hesitation. Somewhere inside its bone-lit corridors, the kingdom's prophesied hero walks toward the same final chamber, certain that righteousness will be enough to survive what waits there. Isolde and Thessaly know better. The maze was built to break monsters apart before they could become something worse together.
Instead, it teaches them how perfectly they fit. With every toll paid in blood and every enemy left burning behind them, their alliance sharpens into obsession. Isolde does not ask Thessaly to be merciful. Thessaly does not ask Isolde to be less monstrous. In a kingdom of crumbling cathedrals, sacred lies, and old prophecies written by frightened men, two women discover that devotion does not have to redeem them to make them unstoppable.
The Hero of Prophecy was promised a kingdom. But what happens when the monsters decide they want the throne?
