Jessalyn Thornton and her best friend, Addison Hammond, visited the uninhabited Thornton Hall on the coastal Georgia for a pre-wedding celebration and sleepover, but the fun ended when Jessalyn disappeared. Now Jessie's friends, family, and coworkers search the undergrowth and abandoned spaces throughout Blackrock Island, seeking any trace that might lead to her whereabouts. That's why paranormal expert Savannah Woodham asked Nancy Drew to investigate potential leads. This case requires a skeptic, someone who isn't afraid of a place where stories of the supernatural hang as thick as Spanish moss from cypress trees. Did the heiress to the Thornton business empire vanish among the monuments, or is someone holding something besides family secrets?
