Vanessa, a freelance writer who grew up in Spain, is † fleeing the pain of an unravelling relationship when she goes to her grandmother's house on Canada's east coast, near Oak Island. Her discovery of a 400-year-old diary written by a failed Spanish Dominican monk rekindles her obsession with an international, multi-million dollar treasure hunt that has drawn investors, including Franklin D. Roosevelt, from Canada, the United States, and Europe for more than two hundred years. Vanessa's arrival at a new solution to the mystery, by learning how to see beyond the barriers of reason, plunges her into an underworld from which there is no turning back. The rules that run the surface world do not apply.
