  "prompt": "A square 1024x1024 image in a dark, moody, and slightly surreal art style, suitable for a literary fiction audiobook cover. The central imagery should be an antique, leather-bound book, closed, lying on a weathered, dark wooden surface. One single, ethereal wisp of smoke or a faint, almost translucent whisper of mist is gently rising from the spine of the book, hinting at secrets or memories contained within. The color palette should be dominated by deep blues, muted purples, and dark, rich browns, with subtle hints of aged gold or sepia for atmospheric highlights, particularly on the book's edges. The lighting should be dramatic and chiaroscuro, with deep shadows and soft, diffused light illuminating the book and the rising mist. The overall composition should evoke a sense of mystery, introspection, and a hidden narrative. The atmosphere should be quiet, contemplative, and slightly haunting. The image should feel professional and artistic, with a painterly texture. NO text, NO letters, NO words, NO title, NO author name.",
