Clara Whitfield has always trusted reason, discipline, and education. Raised in a strict foundling home, she has built her life around independence and the belief that superstition has no place in a civilized society. When she receives an appointment as the new schoolmistress of Oakhaven Ridge, an isolated mountain settlement, she sees an opportunity to escape her past and establish a life of her own.But the moment her carriage reaches the village, Clara realizes that something is deeply wrong.The schoolhouse is surrounded by strange iron reinforcements, its bedroom doors can be locked from both sides, and every mirror is covered with linen before sunset. The villagers obey an uncompromising curfew, barring their doors and shutters before the mountain fog descends. Their elderly leader, Silas Crawford, insists that nobody should walk the parish road after nine o'clock.Most disturbing of all is the warning repeated by the frightened caretaker, Rebecca Sinclair: Never uncover a mirror after dark. Never answer two knocks after midnight. And never open the door to something waiting outside.Clara dismisses these rules as primitive mountain folklore.
