When young governess Lillian Ashford arrives at Blackthorn Manor, she is instantly drawn to the eerie beauty of the estate and the whispers of its dark past. The grand halls echo with secrets, the candlelit corridors conceal shadows, and every night, a ghostly silhouette draped in white silk is seen gliding through the misty gardens.

As Lillian delves deeper into the mystery, she uncovers hidden letters, locked rooms, and a tragic tale of love and deception buried beneath layers of time. The deeper she searches, the more danger she invites—until she realizes that the past is not as distant as it seems. Someone at Blackthorn Manor will do anything to keep the truth buried, and Lillian may be the next to disappear.
