  "prompt": "A square, 1024x1024 professional audiobook cover artwork. The style should be evocative and slightly melancholic, hinting at historical drama and personal journeys. The main imagery is a solitary, gnarled olive tree with sparse, wind-swept branches reaching towards a turbulent, twilight sky. Its roots are deeply embedded in dry, cracked earth, suggesting struggle and resilience. In the far background, barely visible through a hazy, atmospheric mist, are the faint, abstract outlines of ancient, ruined structures, perhaps suggesting lost civilizations or homes. The overall mood is somber yet hopeful, with a color palette dominated by muted earth tones (ochre, sienna, sepia) contrasted with deep blues and purples of the stormy sky, and hints of silver or pale gold light breaking through the clouds. The composition should be dramatic, focusing on the stark beauty of the tree against the vast, expressive sky, creating a sense of isolation and enduring strength. High detail, painterly quality, atmospheric depth. NO text, NO letters, NO words, NO title, NO author name.",
