  "prompt": "A dramatic and atmospheric square image for an audiobook cover. The style should be dark realism with a touch of surrealism. The central image is a lone, weathered oak tree, its branches gnarled and reaching like skeletal fingers towards a stormy, bruised sky. At the base of the tree, partially obscured by tangled roots and shadows, is a single, dark, tattered leather-bound book, its pages unfurled as if caught by a phantom wind. The overall mood is somber and introspective. The color palette is dominated by deep indigos, stormy grays, muted earth tones, and hints of dark crimson or rust in the shadows. The lighting is chiaroscuro, with sharp contrasts between light and deep shadow, creating a sense of mystery and unease. The composition should be balanced but unsettling, with the tree as the dominant, imposing element. The background is a turbulent, abstract sky. Professional audiobook cover aesthetic, square 1024x1024 format. NO text, NO letters, NO words, NO title, NO author name.",
