Clara Bennett, a quiet bookseller, receives a mysterious letter naming her heir to a vast estate she never knew existed. Drawn to Halridge Manor, she uncovers her family’s cursed legacy: a mirror that grants an impossible fortune at the cost of one’s soul. Guided by the ghostly reflection of her ancestor Elara, Clara learns the truth—each Halridge heir has fallen to greed, bound by a centuries-old pact. On the seventh day, she defies the curse by rejecting the fortune and shattering the mirror, freeing every soul trapped before her. Her reward is the only true treasure her freedom.
