A cinematic, professional thriller book cover art in 1024x1024 square format. The scene features a lone, mysterious silhouette of a woman standing on a rain-slicked asphalt road at twilight, facing a vast, blurred landscape of a dark forest and a distant, glowing government-style building. Moody, deep blue and slate grey color palette with sharp highlights of amber from a flickering street lamp. High contrast, film noir atmosphere, hyper-realistic texture, sharp focus on the silhouette, blurred bokeh background. The composition is minimalist and intense, evoking feelings of suspense, mystery, and espionage. No text, no letters, no words, no titles, no author names, no logos.
