Relia has spent her life content to be in the shadow of Princess Dawn. Even a hundred years of separation could do nothing to diminish their love. Because their enemy, Lire, gave Relia a chance to return to Bearra upon its waking. But she never told Relia the true cost: that she would be disguised as Carlotta, a maid, and placed to spy on Dawn. And when Dawn is told of a mirror that can reveal Lire's hidden spies - other girls like Relia brought back to life by the fairy - Relia realises her days are numbered. They travel the world to find the mirror, but Dawn's emotional state is in decay as the weight of being the perfect princess crushes her, and 'Carlotta' is a comforting reminder of the love she lost. Their kingdom isn't the only thing that's falling.
