Hakon,the teenage King of the Vikings, has defeated his rival and brother, Erik Bloodaxe. Erik had been ravishing the lands and left a bloody trail. Rather than kill his brother, Hakon makes him vow to leave and never return. Hakon then travels with part of his followers and warriors to the Uplands, to fulfill the vow he has made to the Jarl of that area. He is to marry Groa, the daughter of the Jarl. He detests the woman, but he had promised to wed Groa to secure the backing of her father in the fight against his brother, Erik. The Jarl is ill, but manages to live long enough to see the pagan ceremony before dying. To make the marriage valid Hakon must have sex with her in front of female witnesses. He imbibes too much at the feast to execute the actual act. When both are unclothed and in bed, Harkon rolls over vomits twice, and collapses. When he awakes in the morning, he leaves his bride who is not his wife, and his warriors. The son of the Jarl refuses to swear allegiance to Harkon. Once Harkon is a good distance from the Uplands Hall, he send Groa and her retinue back. Upon his arrival at his Hall, he discovers the Captain of a kraal has delivered twelve monks from Engo-land, but refuses the silver promised. Hakon rescues the monks from his suspicious followers and gives them a thatched hut and permission to build a church. His pagan subjects are furious and Sigmund, the powerful Jarl that has been his mentor is furious at his not completing the marriage and the monks. Hakon must repair the damage between Sigmund and himself, fight the Dane that raids his lands, and the son of the Uplands Jarl that has wed his mother to a much younger Dane. All but one of the monks is burned to death and once again Hakon must prove his worth in individual battle before others will follow him to destroy the Dane that has raided his lands for years. Will his plan to bring Christianity to the Norsemen fall by the wayside or will he somehow once again succeed in battle? This book delivers excitement and page turning events as a young teenager matures.
