That sounds like something I'd enjoy reading. I love historical fiction. I really enjoyed Geraldine Brooks' Year of Wonders, for instance. I just finished a thomas Hardy novel this morning, though I think he wrote about his own time period?

It is interesting that we hear so little about women of the Viking culture. I've wondered about the lack of data myself. Were the women really so insignificant?

Good luck with the writing and editing, and I hope you do find a good publisher.
