  "prompt": "A highly detailed, atmospheric, and moody digital painting for a book cover, square format (1024x1024). The style should be evocative of dark romanticism or psychological thriller. Dominant imagery features a single, intricately carved wooden mask, half-obscured by shadows, resting on a dark, polished wooden surface. A faint, ethereal glow emanates from behind the mask, hinting at hidden depths or secrets. Subtle wisps of dark smoke or mist curl around the edges of the mask. The overall color palette is deep, rich jewel tones – emerald greens, sapphire blues, and ruby reds – contrasted with deep blacks and charcoal grays. The lighting is dramatic, with strong chiaroscuro, casting long, sharp shadows. The mood is mysterious, intriguing, and slightly unsettling, suggesting a complex narrative with elements of deception and hidden emotions. The composition is tight, focusing on the mask and its immediate surroundings, creating a sense of intimacy and intrigue. Professional audiobook cover aesthetic, no text, no letters, no words, no title, no author name.",
