A professional book cover for Ken Follett's "Un loc numit Libertate" audiobook. The visual style should be gritty and historical, evoking the 17th century. The main imagery should feature a silhouette of a stormy sea with a powerful sailing ship battling the waves in the background. In the foreground, a pair of hands, one rough and calloused (suggesting a rebel or laborer) and the other more refined but also determined, are reaching towards a single, flickering flame of light or a stylized, broken chain. The color palette should be dominated by deep blues, grays, and blacks for the sea and sky, with accents of warm, muted gold or amber for the light/flame and hints of muted earthy tones for the hands. The overall mood should be one of struggle, hope, and resilience against overwhelming odds. The composition should be dynamic, with the ship and waves creating a sense of movement and danger, while the hands and light offer a focal point of human spirit and the pursuit of freedom. The typography for the title and author's name should be elegant but strong, fitting for a historical epic. Aspect ratio: 1024x1024.
