A square, professional book cover illustration in a painterly, slightly melancholic style. The dominant imagery should be a vast, still sea stretching towards a dawn sky. Gentle, muted waves lapping at a deserted, pebble-strewn beach. In the foreground, a single, weathered wooden chair sits facing the sea, conveying solitude and contemplation. The color palette should consist of soft blues, grays, and pale oranges/pinks of a very early sunrise, creating a mood of quiet reflection and underlying resilience. The lighting is diffused and soft, hinting at the dawn. The overall atmosphere is serene yet imbued with a sense of poignant memory and waiting. No text, no letters, no words, no title, no author name. Aspect ratio 1:1.
