Imagine an ebook cover with the theme of time traversal. En el centro de la imag

Imagine an ebook cover with the theme of time traversal. En el centro de la imagen, there is a futuristic time travel device, bright and full of lights and buttons. He is floating in the middle of a colorful vortex, representing the flow of time. The vortex is composed of vibrant shades of blue, purple and green, with lines of energy emanating from the device and extending in multiple directions, creating a feeling of movement and dynamics. Ao fundo, different time portals are open, showing glimpses of various eras – from prehistory with dinosaurs, passing through ancient civilizations such as Egypt and Rome, even futuristic scenarios with skyscrapers and spaceships. Each portal is enveloped in a halo of light that highlights the different eras, connecting them to the central device. The ebook title is in a modern, stylized font, placed at the top of the image, with a smaller subtitle below. The author's name is at the bottom, complementing the cover composition. The image conveys a sense of mystery and adventure, capturing the essence of temporal exploration.
