In the atmospheric heart of South Louisiana, Evangeline "Evie" LeBlanc, Curator and Archivist for the Bayou Teche Historical Society, finds her world of folklore, oral histories, and natural history violently upended. Living in her Mémère Alysse's cabin, Evie is no stranger to ghost stories, but as the "thirteen days" countdown to All Hallows' Eve begins, she becomes the unwilling target of a real-life mystery. A meticulously unsettling secret admirer starts dispatching a series of increasingly eerie gifts, each drawn directly from the most disturbing legends within Evie's own museum archives. Supported by her loyal friends-the jocular Remy, the vibrant Sylvie, and the steadfast, handsome Beau-Evie must harness her unique archival expertise to decipher the chilling clues woven into these macabre presents. This journey into spooky intrigue promises an unforgettable blend of Louisiana gothic mystery and burgeoning romance. As Evie races against the clock to unmask her shadowed suitor, she also begins to realize that the deep, abiding love she seeks has been by her side all along. Ultimately, she discovers a profound new relationship with Beau, all while honoring her Mémère's memory through the enduring traditions of the season.
