Ashley, Rose, and Cathee, three preteen friends from Portland, Oregon, take off on a trip to visit family in France. At just 12 years old they expected fun, fashion, and adventure, though not the heart-pounding, gut-wrenching kind they run into. As they discover and try to solve strange mysteries, they stumble upon a terrifying secret an entire village hides from. In a race against time where not just their lives, but even their souls are threatened, the girls end up face to face with a mortal danger which will test their strength, courage, and intelligence in ways they could never have guessed.
