Science Fiction Bright Modern Secure Book Cover Ideas with Mountains City Horizon Skyscrapers Globe Architecture Streets

A modern, futuristic city is depicted encapsulated within a transparent glass globe resting atop a grand, geometrically intricate and fortified architectural base. The globe contains a detailed miniature urban scene with high-tech skyscrapers, clean streets, and a radiant sunlight horizon breaking behind the scene, showcasing distant towering mountains. Surrounding the globe, glowing energy lines and digital grids create a sci-fi aesthetic. The backdrop is kept minimalistic, showcasing a subtle gradient from deep space-like hues to a glowing, optimistic horizon.

Bold sans-serif font for the main title "Vision and Strategies," with a futuristic metallic gradient effect. Subtitles and smaller text are in a clean, geometric sans-serif typeface, with uniform spacing and capitalized letters for consistency.

The main title is centered on the top part of the book with glowing sci-fi accents beneath it, while the small text ("of sustainable urban development and design") is arranged below the globe in a neat and balanced semicircular shape. The primary image (the globe city inside the architecture) dominates the center of the cover, with the bright horizon creating a visual anchor near the bottom. The background uses negative space to draw focus.
