When Katherine Katrinova, the heiress to the oldest and darkest family in Russia is sent to Hogwarts instead of Koldovstoretz through an act of spite by her mother, she expects nothing more than a substandard education and frequent bouts of homesickness for Russia and her friends. She's not completely wrong, but she hadn't expected to befriend four boys with a passion for mischief, or to find herself neck deep in a blood purity war. Will she be able to continue honoring her family and culture across the continent? Will she be able to keep the rest of the world out of the war that threatens to ruin Britain? And will she be able to escape the darkness that runs through her blood, or will she finally surrender to it?
