Fantasy Black Green Mysterious Book Cover Ideas with Forest Girl Mist Moon Boy Faces Orbs Tree Branches

A boy and a girl are back-to-back, their profiles faintly illuminated by a mystical greenish glow. Both faces are partially obscured by swirling mist and shadowy, creeping tree branches that extend inward from the edges of the cover. The branches form an enigmatic frame around them, blending into a dense forest that fades into black at the edges. Small specks of glowing green orbs appear, like will-o'-the-wisps, scattered in the background to enhance the lively, fantasy atmosphere. A faint celestial aura hovers overhead amidst the darkness—the suggestion of a rising or setting moon partially hidden by the branches above.

The book title, "The Last King," is written in a bold, serif font with sharp, angular edges, glowing faintly in green, giving an ethereal, magical effect. The author’s name, "Violet Fulton," is written in a smaller, delicate serif or sans-serif font at the bottom in white. The font style evokes simplicity while complementing the mystical ambiance of the title font.

The boy and girl stand centered, forming the focal point of the design. The tree branches frame both sides of the cover, creating a natural border. The title is placed prominently at the top, with a slight arch to follow the subtle curve of the branches. The author’s name is understated but legible, located along the bottom edge of the cover, unobtrusive to the main imagery.
