The Queen of Winter assures her it will at last bring an end to the war. But while masquerading as a new student at Summer's Academy and joining Kelcie and her fianna in martial training, Lexis' conscience (as well as her dedication to her mission) is seriously challenged by claims that the artifact's theft would actually destroy Summer utterly.
