The Sea's Edge

In 1030 C.E., Cnute, king of England, Denmark, and Norway, sends Harald, his middle son, to the Kingdom of Dublin to meet with his Norse-Irish allies. Harald’s mission is to coordinate an invasion of the northern Welsh kingdom of Gwynedd, to replace King Rhydderch who is growing too powerful on England’s borders. Harald is reluctant to be involved in affairs of state, but agrees to go, even though his beloved wife, Selia, is unwell. Harald tells Selia he will not have to take part in the fighting.
While she waits for Harald to return, Selia and her friend Gudrun befriend a young and attractive gleeman (poet-minstrel). When the gleeman is accused of a crime, Selia seeks witnesses in his defence.
Harald becomes involved in a conflict with Dublin’s neighbour, and to appease the king of Dublin, he commits to leading their combined forces in the attack on Wales.
