But when Hedan falls in love with Bilihild, a young Christian maiden, he offers peace to his Christian subjects if Bilihild will become his wife. As Bilihild strives to love her new husband and protect her people, she faces increasing difficulty and danger, especially from her jealous mother-in-law. As the clouds thicken around her, Bilihild must put her entire reliance on the God whom she honors and loves. (Summary by bookAngel7)
