In the remote mountain village of Elmwood stands an ancient stone watchtower, tended for generations by a single guardian. When young Mara inherits the duty from her ailing grandfather, she discovers a hidden journal revealing the tower's true purpose—it does not watch for storms or invaders, but for something far older stirring in the surrounding forest. As strange lights appear at night and villagers begin to vanish, Mara must unravel centuries of buried secrets, confront the elders' lies, and decide whether to protect her people from the truth—or from what the truth has awakened.
