Act as a seasoned novelist with expertise in magical realism and speculative fiction. Craft a compelling narrative about a protagonist who possesses the unique ability to see the future, but only through the ebb and flow of tides. Describe their struggles, the societal impact of their gift, and how they navigate a world that both reveres and fears them. Include [COASTAL_SETTING], [MYSTERIOUS_EVENT], and [PERSONAL_CONFLICT] as key elements in your story. Ensure the tone is atmospheric, blending wonder with melancholy, and explore themes of fate, isolation, and humanity's relationship with nature.
