But news of their disappearance forces Hattie to leave England and embark on a voyage that will reveal the long-buried secrets of her past. An encrypted senet board and a gold medallion lead Hattie on a perilous quest to track down her missing parents--and discover why people associated with the Blackhouses continue to turn up dead. What she uncovers is a secret that could alter the course of history.
