  "prompt": "A dark, moody, and atmospheric square image (1024x1024 pixels) suitable for a professional audiobook cover. The central focus is a single, deeply velvety black rose, its petals unfurling slowly, revealing an almost imperceptible shimmer of deep crimson or indigo at the edges. The rose is positioned slightly off-center. Behind the rose, a subtle, ethereal mist swirls, suggesting depth and mystery. The background is a gradient of deep, rich, bruised purples and midnight blues, with faint, almost ghostly hints of silver or moonlight filtering through the mist, creating a sense of shadows and hidden luminescence. There should be a palpable sense of gothic romance and introspective melancholy. The lighting is dramatic and chiaroscuro, highlighting the texture of the rose petals and casting soft, elongated shadows. The overall mood is one of elegant despair and forbidden beauty. No text, no letters, no words, no title, no author name.",
