Highland moon sifter

Bekah McRafferty has one goal. Travel back in time and kill the Moon Sifter Shaw Limont so that billions of the human race can survive. Yep, that was the plan until she actually meets the Highlander. He's not exactly the evil guy history made him out to be. Creator of monsters that nearly ate mankind to extinction? Well, maybe, Maybe not. But now that she's jumped into the 13th Century with the future of humanity depending on her to keill the guy she's rapidly falling for, and with monsters on her tail, trying to stop her, what's an assassin to do?
