RetroSci style. A book cover with the title: “Starlight Sirens: Escape from Xylon 7” in a large, metallic, and bold font with sharp edges, radiating a neon glow in vibrant pinks and blues. The letters look almost like they’re made of chrome, catching the light from distant galaxies. In the center of the cover, two stunning women clad in form-fitting, futuristic space armor stand atop the wreckage of a spaceship. One holds a laser rifle aimed off-screen while the other looks defiantly into the distance, her hand resting on a glowing alien artifact. Surrounding them, an alien planet with jagged, dark rocks and towering neon-blue crystalline formations. Above them, two massive moons hang in a purple sky. In the background, the remnants of a gigantic spaceship loom ominously, partially buried in the rocky landscape. Vibrant colors with a heavy use of deep purples, neon pinks, and blues to give that iconic 70s space-opera vibe. The lighting is dramatic, with highlights reflecting off armor and crystals. Dust clouds swirl beneath the characters, adding action and depth.
