Summary: Rhian Morrigan lived the first few years of her life in happiness and peace and love with her family. Until one Christmas Eve night a stranger knocked on their door and kills her mother. Rhian was homeschooled until the year she turned 16, then she was sent to Hogwarts. On the train she meets a strange friend, who has alternate motives.
