**Alt text:** Promotional graphic for *Her Dark Grave* by Carolyn Arnold, Detective Madison Knight Book 12. The image features the ebook, audiobook, and paperback editions displayed against a moody landscape of a long, rain-darkened road winding through dense forest. Heavy storm clouds loom overhead, casting a chilling and foreboding atmosphere across the scene. Across the top, text reads, “A Chilling Crime Thriller and Police Procedural.” A “Buy Now” button appears in the lower right corner. The isolated roadway, dark skies, and remote setting suggest buried secrets, looming danger, and a suspenseful investigation that leads into the unknown.
