Servant of Evil

If you have listened to the song then you'll pretty much know the plot. It is based off the song 'Servant of Evil' by Vocaloid with some of my own assumptions and twists.

Rin at the age of only fourteen is forced to be Queen in an unstable time and country. With her twin brother missing, the only one she truly rely on and trust will she ever be able to keep the crown steadily on her head.

P.S. my first book so please no hate only options for improvement and positive comments.
