A cinematic, atmospheric square image (1024x1024) suitable for an audiobook cover. The scene depicts a rugged, sparsely populated Australian coastline at twilight. Crashing waves are a prominent element, with white foam against dark, turbulent water. The land is characterized by dry, windswept scrub and rocky outcrops, suggesting isolation and harshness. In the distance, a faint, melancholic glow emanates from a single, small building or lighthouse, hinting at human presence but emphasizing solitude. The sky is a dramatic gradient of deep indigo, bruised purples, and hints of dying orange and red near the horizon, with a few scattered, wispy clouds. The overall mood is brooding, mysterious, and tinged with unease. The lighting is low-key, with strong contrasts between light and shadow, enhancing the dramatic and tense atmosphere. The style should be realistic but with an artistic, painterly quality, evoking a sense of foreboding and the raw power of nature. No text, no logos, no human figures are visible.
