In a world where magic is mostly gone, the story follows Celaena Sardothien, a teenage assassin who has been imprisoned in a brutal labor camp. The Crown Prince offers her a deal: compete in a deadly competition against thieves, soldiers, and killers to become the King’s Champion. If she wins, she earns her freedom.
But inside the glass castle, the competition quickly turns deadly in a different way. Contestants begin dying under mysterious circumstances, and Celaena realizes something far more dangerous than the competition is hiding within the kingdom. As she investigates, she is forced to balance survival, loyalty, and uncovering a dark force threatening everyone she starts to care about.
