  "prompt": "A professional audiobook cover illustration, square 1024x1024 format. The artwork should evoke a sense of classic, timeless elegance and familial drama. The central imagery should be a grand, weathered stone manor house, partially obscured by mist or soft, diffused light, suggesting it's seen many years and holds many secrets. Surrounding the manor, depict a lush, wild garden with elements like climbing ivy, antique roses, and perhaps a hint of a winding stone path. The overall mood should be slightly melancholic yet warm, hinting at deep emotional currents. The color palette should consist of muted, earthy tones: soft greens, greys of stone, deep blues of twilight sky, and touches of faded sepia or antique gold. The composition should be balanced, with the manor as the focal point but with enough surrounding detail to create depth and atmosphere. The style should be painterly, with visible brushstrokes, reminiscent of traditional oil paintings. No text, no letters, no words, no title, no author name, just the visual artwork.",
