Throne of Glass (Steklyannyy Tron)

From childhood, she was trained to kill. By eighteen, she had become the most famous female assassin in the entire kingdom. And even from the grim dungeons where she was exiled, her name continues to inspire fear and awe. Celaena Sardothien. A cold-blooded criminal and a charming captive whose strength and abilities may be needed by her enemies. But first, she must prove her superiority in a tournament in a glass castle. This is the only path to freedom in a land where the king has ordered the destruction of ancient knowledge and where even the mere mention of magic is cruelly punished. But magic cannot be eradicated by force; it can manifest unexpectedly. Just like love.
