Douglas Eagle Greyeyes, shapeshifter and member of the Blackfoot tribe, rescues a beautiful woman, but the signs in the stars tell him her arrival in his world is not accidental. His mortal enemy will soon attack, and the woman could either save or destroy him. Vanessa O'Casey witnesses her mother’s hit-and-run death. Descended from Irish Travelers, she and her mother never settled anywhere, and Vanessa finally realizes they were running from someone. But she never asked to be sent to another time. When the killer finds Vanessa, she and Greyeyes must fight-not just for their lives but against their growing attraction-if they are to defeat a common enemy as powerful as the forces of nature.
