Catriona O’Connell has been hired to steal a mysterious book from Aidan Douglas, Earl of Kilronan. But Cat is secretly Other, an age-old mixture of Fey and human—something Aidan recognizes immediately when he surprises the lovely young burglar in his library, about to steal a magical diary. . Cat’s spirited beauty enchants him, but her uncanny abilities are what he truly needs, for Cat can understand the mystical language in the diary he inherited from his murdered father. So Aidan makes an offer: translate the book or be thrown in prison as a thief. And as Cat slowly deciphers each page, she and Aidan are drawn together by passion . . . and into the violence of the Other world that is the Kilronan legacy.
