Kate Callaghan’s ‚Crowned A Traitor‘ is literally a hell of a book: its main protagonist Klara is none other than Lucifer’s daughter who is destined to be his heir as ruler of Hell. There are just two problems. Klara really, really doesn’t want to rule Hell. And while this book starts off really strong, the ending is completely unsatisfying because it’s so exaggeratedly surprising. The big revelations appear so much out of nowhere that it feels like cheating – therefore, only three stars.
