Vikings have attacked Jena's village in the past, but they were prepared. They had fought and won. This time they were taken by surprise, and the reward for their quick submission; protection from future attacks.
The price; eight of their women.
Jena will not watch the people she loves get taken by Vikings. Standing up to the massive men, she offers herself in their place, no fight.
Aboard the Vikings' ship, Jena learns what it means to feel pleasure and power at the hands of eager Vikings let loose, and finds herself wanting more and more.
