A square, 1024x1024, professional audiobook cover art. The image depicts a vast, frozen Siberian river landscape. In the foreground, a weathered, open journal lies partially buried in snow, its pages faintly illuminated from within by a soft, ethereal light. The river itself is a serpentine ribbon of ice and muted blues, reflecting a pale, distant sun. Distant, snow-capped mountains fade into a hazy, muted horizon. The overall mood is melancholic, contemplative, and slightly mysterious, with a color palette dominated by cool blues, icy whites, deep grays, and a touch of warm, internal glow from the journal. The composition should be evocative and atmospheric, conveying a sense of isolation, memory, and the passage of time. No text, no letters, no words, no title, no author name.
