A square, professional audiobook cover art in 1024x1024 resolution. The style is surreal and slightly melancholic, with a touch of retro-futurism. The central image depicts a solitary, slightly dilapidated carousel horse, cast in a muted, desaturated color palette of dusty blues, greys, and faded golds. The horse is positioned off-center, looking towards a vast, hazy industrial cityscape in the background, rendered in silhouettes of smokestacks and distant, shadowed buildings. A single, weak, warm light source, perhaps a distant streetlamp, casts long, distorted shadows that stretch across a cracked, uneven pavement in the foreground. The atmosphere should evoke a sense of abandonment, faded grandeur, and quiet desperation, without any text, logos, or legible elements. The overall mood is introspective and subtly unsettling.
