Realistic Vector Book Mockup

Generate a hyper-realistic image of two black books, one floating above the other, against a dark grey background. The top book is positioned at an angle, with its cover facing the viewer, displaying the text 'REALISTIC VECTOR' in thin, gold font at the top, '.EPS' in a gold starburst shape below, and 'BOOK MOCK UP' in bold, gold font at the bottom. The lower book lies flat, slightly angled to the right, with its white pages visible along the right edge. The books cast subtle shadows on the dark grey surface below, with soft, diffused lighting emphasizing the texture of the book covers and the metallic sheen of the gold text. The overall composition is sleek and modern, with a focus on showcasing the book mockup design. The image should be highly detailed, with realistic textures, accurate lighting, and refined styling, resembling a high-end design editorial or campaign photograph. The dark grey background should be subtly gradated, with a slight shadow effect around the books to enhance the sense of depth and dimensionality. The result should be a visually striking and professional image that effectively showcases the book mockup design.
