They were born three thousand years apart, but fate brought them together.

Dragged into the ancient past by a crashing spaceship, Tor and his fellow Vikings face starvation in an autumn that is six months too early. When exploring their new home, they meet the mysterious Kiana and the villagers whose winter shelter has been destroyed by the spaceship.

Uneasy allies at first, these two leaders find unexpected love as they join forces to build a home together, until Kiana's enemies threaten her new life.
