Lucia Ingegärd is an American of Italian and Nordic descent. Or at least she was an American until she was transported to a time long before her country existed. Desperate to return to the future before Christmas, Lucia puts her engineer's mind to the singular focus of going home. Her work is stalled when a huge, fierce-looking warrior surrounds her temporary home and gives her an ultimatum: surrender herself or she'll be shown no mercy.
