Uncrown: I Made a Contract with the Evil Prince

Ashen is a lady of the house Altaris, a clan of mages from the north. She is a candidate for the throne, one of the five chosen ones who were born to fight to steal the crown. When the representatives met the legendary seer, they were each shown the possible futures of their reign if they ever won the battle royale. When Ashen finally spoke with the seer, she was hit by the news that the whole world will fall into complete ruin if she ever fails to become queen, but how can she take the throne when she is forced to forfeit her claim and become the Assassin of the Prince? She made a mistake, and now she is bound by blood to be the sword and shield of the prince with the darkest heart.
