The Secrets of the Old Post Cemetery is the much-anticipated third book in the Ohnita Harbor Mystery series, reuniting readers with beloved protagonist Gabriela Domenici, the smalltown librarian and authenticator whose accidental sleuthing puts her on the frontlines of death and danger. The book opens with an historical prologue, dating back to the American Revolution, a narrative thread that weaves into a modern-day story about The Traitor's Map— a highly inaccurate spy map that could be a hoax, a ruse used against the British, or a poor attempt by an 18th century amateur cartographer. After Gabriela shows the map to a group of college students, one of them is found murdered on the lakeshore— triggering a spiral of death and deceit that shockingly embroils Gabriela and the man she loves. Written as a standalone, The Secrets of the Old Post Cemetery tells a riveting story with emotional complexity as it explores love, betrayal, murder, and a chance for redemption.
