In the Twelve Realms there lives a man who covets life. He lurks in the shadows, intent upon stealing the one thing sustaining his perpetual existence: true beauty. Princess Caityn's loveliness reaches from what the eye sees to the very marrow of her soul. The thief's covetous heart desires the life her beauty possesses and will stop at nothing to take it all.
