A square, 1024x1024 AI-generated image for a book cover. The visual style is dark, moody, and slightly surreal, evoking a sense of introspection and transformation. The central image is a human silhouette with increasingly dog-like features merging from its form – perhaps the lower half of the body transitioning into canine legs, or the face subtly shifting into a muzzle. This transformation should feel organic and a bit unsettling. The background is a muted, urban landscape at twilight or dawn, with blurred lights and indistinct shapes, suggesting isolation and a journey through an unfamiliar reality. The color palette is dominated by deep blues, grays, and muted purples, with subtle hints of warm light in the distance, creating a melancholic yet intriguing atmosphere. The composition is centered, drawing the viewer's eye to the central figure and its transformation, with a sense of depth and vastness in the background. The overall aesthetic is professional and artistic, suitable for a thought-provoking novel. NO text, NO letters, NO words, NO title, NO author name — only visual artwork.
