A book cover The cover features Valentina, a young mage, seen from behind with long, black hair. Her face and skin tone are hidden. She is standing in a devastated, post-apocalyptic cityscape, with ruined buildings and a dark, ominous sky. The background combines elements of futuristic technology and ancient magic, with glowing runes and broken machinery scattered around. Valentina is holding a staff or magical artifact, with a faint aura of power surrounding her. The overall mood is intense, dark, and mysterious, hinting at the epic struggle and the clash of magic and technology.
