Ten years ago, Serene was sent away to a distant place to heal, leaving Mourndale behind. Now she returns, but the town she knew is gone-replaced by a quiet, unsettling shadow where people wear familiar faces yet feel strangely wrong, and the night hides horrors that bleed black. Haunted by fragmented memories and visions of a girl she cannot place, Serene is drawn into a dangerous truth she was never meant to uncover. With the help of a mysterious investigator she once considered an enemy, she follows a trail of secrets left hidden within her own home, revealing that she was never meant to come back. As ancient powers awaken and a forgotten bond calls out to her, Serene slowly realizes that her return was not an accident... and that the one controlling the darkness is the very last person she would ever dare to suspect.
