Auction house appraiser Jude leaves London for her dream job at Starbrough Hall, an estate in the countryside, examining and pricing the manuscripts and instruments of an eighteenth-century astronomer. The timeworn tower that lies nearby. The tower was built as an observatory for astronomer Anthony Wickham. A nightmare begins to haunt Jude's six-year-old niece-- the same nightmare Jude herself had years ago. Is it possible that the dreams are passed down from one generation to the next? What secrets does the tower hold? And will Jude unearth them before it's too late?
