An elegant book cover for 'An Unknown Garden' depicting three young figures walking towards a mysterious gate in an overgrown, moonlit garden. An open Korean book glows on a mossy bench, and a white pill lies on the stone path.

Create a mysterious, elegant, classic novel cover inspired by The Secret Garden, but as an original sequel. The setting is an old English garden at twilight, overgrown with ivy, roses, and hidden pathways. The atmosphere is mysterious and emotional rather than frightening. In the foreground, three young figures—Colin, Mary, and Dickon—are walking toward a forgotten stone gate, searching for the truth behind Colin's mother's death. Their faces are partially hidden to create intrigue. Subtle clues should be woven into the scene: A small white pill lying on an ancient stone path. An old Korean medical book resembling the Donguibogam (동의보감) resting on a moss-covered bench, its pages slightly open and glowing softly. Moonlight filtering through dense trees. Vines forming hidden shapes, suggesting secrets buried in the garden. A vintage botanical illustration style mixed with realistic painting. Color palette: deep emerald green, dark teal, antique gold, muted ivory, and soft moonlight silver. Typography: Main Title (large, elegant serif): An Unknown Garden Subtitle (smaller, italic): A Working Title: The Secret Hidden Beneath the Garden Author: Park Jiwoo The overall feeling should resemble a bestselling literary mystery with historical elements, combining the beauty of a secret garden with the suspense of uncovering a hidden truth. The design should be sophisticated, timeless, and suitable for readers aged 12 and above. Ver mais
