Swept Away- a time travel thriller by Susan Kiernan-Lewis

http://www.amazon.com/gp/product/B00A6KGLCU

After Ella Stevens begins a new job in Germany, she stumbles onto a time portal that takes her to 1620 Heidelberg where all her modern day techno-toys and proud self-reliance can’t protect her from the brutal realities of everyday life.  Befriended by a convent of nuns who live in fear of the bloodiest warlord in Europe, Ella struggles to survive.  With the help of a sexy US Marshal who follows her back in time, she learns the hard way that when it comes to the things that really matter in life — love, trust and friendship — sometimes opening yourself up to others is the only true way home.
