A teenage assassin, a rebel princess, menacing gargoyles, supernatural portals and a glass castle prove to be as thrilling as they sound. Being the most feared assassin in Adarlan is a notoriety 17-year-old Celaena considers an honor, even though it has landed her in a slave-labor prison no one has ever survived. A year into her sentence, the Crown Prince offers to sponsor Celaena in a competition with 23 other criminals and murderers that, should she win, will result in her freedom. The only catch? She'll become the king's personal assassin for four years, the same dark-hearted king who sentenced her to imprisonment.
