Fall has arrived in Bannon Mills, and librarian Dawn Keen is determined to make the first annual Red Oaks Thanksgiving Cookbook Contest a success. The town is buzzing, recipes are pouring in, and the leaves sprinkle the graying world with color. But just as the excitement peaks, a new ghost begins haunting the library, and it has no intention of staying quiet. Dawn's life goes sideways again as she teeters between a romance she swore she didn't want and another she can never have. To make matters worse, the new spirit seems determined to turn the library into a nightmare of supernatural riddles. Each eerie clue brings Dawn closer to a terrible secret buried in Bannon Mills's past that could upend the community and expose one of their own. With Mae's sharp humor, Charles' protection, Ethan's steady support, and a determined spirit demanding justice, Dawn must solve the mystery before Thanksgiving arrives or risk letting a killer walk free.
