Sad Young Adult Book Cover Design (Featuring girl, silhouettes, and boy)

Visuals: The cover features a dark brown background with a faded, melancholic texture. At the center, there is a large golden apple glowing softly amidst the darkness. On the left side of the cover, a sad girl facing away, with her silhouette partially blending into the background. On the right, a boy looking in the opposite direction, also partially blending into the darkness. A faint connection between them is hinted at by subtle light lines.

Typography: Elegant serif font for the book title, capturing a classic yet emotional feel. The author's name in a simple, clean sans-serif font below the title, smaller in size.

Layout: The title "Forever isn't that long" at the top center, in large serif font. Below the title, the golden apple as a focal point. At the bottom edges of the cover, the girl on the left and the boy on the right, facing away from each other. The author's name "Bella Margaret" at the bottom center in a smaller, sans-serif font.

Explanation: The visual composition evokes a sad yet hopeful feeling with the dark brown background symbolizing the depth of emotions mingling with the warm glow of the golden apple, which hints at enduring hope and longing. The separation of the girl and boy captures the romantic yet melancholic aspect of the story. The typography's elegant serif font for the title conveys a sense of timeless emotion, while the sans-serif font for the author's name creates a subtle balance. The matte finish adds a sophisticated touch, and the embossed title adds dimension and texture, making it stand out visually and physically.
