Sepulchre by Kate Mosse

The novel intertwines two narratives set in different time periods, one in the late 19th century and the other in the present day, both centered around the mysterious and atmospheric region of Languedoc, France. The story follows Léonie Vernier, a young woman in 1891 who discovers a deck of tarot cards and a sepulchre with a dark history, and Meredith Martin, a contemporary American researcher drawn to France by her own personal quest. As their stories unfold, they become linked through themes of destiny, family secrets, and the supernatural, with the past and present converging in a suspenseful tale of intrigue and mystery.
