Historian Bree Kirkland has always been in love with the past, but when she accidentally wakes an ancient Scottish warrior who's spent the past 150 years sleeping in her backyard, her present is suddenly fraught with danger. Faelan has awakened from the time vault, grieving for his lost family, wondering who sent the woman to wake him. If she's a demon, Faelan will have to kill her. If she's innocent, she's unleashed the gates of hell in her backyard. Either way they must rely on each other to save their future.
