The story is set (if I remember correctly) in the time of the Vikings or just before, and located in the area the Vikings hail from. I am unable to remember the Author or if the story was a solo or the plot is a segment of a part work.

While it begins with the main character seemingly being the youngest child of a high ranking member of a fishing Village, the men folk also loot other settlements, via the water courses.

The MC disappeared in a bad storm, can't remember if they were on the sea or on a headland and was washed out to sea.

MC resurfaces (excuse the pun) as late teen (maybe early 20's) but definitely adult, female that the village folk say resembles one of their deities.

i have more, but I am not sure from this point if I am confusing other story plots.

Can anyone help?
