Tired of thinking about her worthless ex-boyfriend and the humiliating way in which they parted, Martha Bigalow goes on a hike hoping the dramatic hills of the English Lake District will help her to forget. But as she crosses an ancient set of stepping stones, she slips and falls into an angry river. Time Travel. Sideways. She wakes in cave, wearing nothing but her dodgy, mismatched underwear. Her only company is the man who saved her life: a tall, dark, and disturbingly attractive stranger named Vadim. Too bad he's a medieval re-enactor gone feral. Or so she assumes. But this is no crazy dream. When Martha fell into the river she--somehow--left the twenty-first century far behind... and medieval Erde is nothing like home. Now, all that stands between her and almost certain death is the crazy man with the sword. And then he offers her his protection... with the role of his "wife." Vadim is a wanted man. An outlaw. The last thing he needs are any complications of the female kind, but then he happens upon a strangely attired woman lying beside the river... Martha is bold, outspoken, and altogether irreverent, and every instinct he has warns him to abandon her... only he cannot. Her allure is already much too strong. Against his better judgement, despite all the risks, Vadim offers to help Martha find her way home. Until then, Martha must adapt to medieval society, steer clear of the Evil Earl and his minions, and maybe--just maybe--learn how to trust her heart again.
