Throne of Glass
Magic is no longer of this world, and a vicious king rules the land from his castle of glass. Celaena Sardothien is an assassin who has a chance at freedom from her sentence of hard labor if she acts as the Crown Prince’s champion in a fierce competition to find a new royal assassin. But soon competitors start mysteriously dying one by one, and Celaena must root out the source of evil before she too becomes a victim.
