From Viz:
Freya thinks of herself as a simple village girl, but her idyllic life is shattered when she is caught up in the aftermath of a treacherous Sigurdian plot. She bears a striking resemblance to her country’s beloved Prince Edvard, who lays dying from poison. Without its ruler, all of Tyr will quickly be engulfed by Sigurdian violence. Now Freya must take Prince Edvard’s place and lead his valiant knights in defending the realm.
