I don’t read historicals. I’m not sure about your Vikings series…
The Edge books aren’t historicals. They’re set far in the future, after huge storms over the course of decades raised the sea level all over the world and sent what few people remained high into the hills for safety. My raiders are like Vikings in that they’re alpha warriors always ready for battle. They take over settlements when they like and always do as they please, sailing the treacherous seas from their island stronghold to rampage at will.
If anything, they’re like an outlaw biker club… but with swords (because guns are iffy after being underwater for decades), swift and deadly raider boats, their very own sense of honor, and a fierce, unswerving loyalty to their clan.
Why not try this excerpt of the first book in the series, Edge of Obsession, and see what you think?
