Ellie, a master of archeology, came to Mist Town to trace the truth behind her mother's mental breakdown. The abnormal rotation of the copper compass led her to the highway where "Mist Hidden Accidents" occur frequently, the bookstore with hidden secrets, and the mine altar oozing black slime. She meets Sheriff Jack, who is searching for his missing wife, and Lucy, a night-blind nurse who can see "luminous threads." The three find that the clues they are pursuing all point to the corrosive power of the black crystal. When the seventy-third cycle countdown sounds, will you become the heart of the sacrifice, or will you break your fate? Ellie held on to the silver hairpin left by her mother. The compass pointer was pointing at her beating heart, where the overlapping faces of her ancestors and her mother three hundred years ago were reflected.
