Act as a seasoned novelist with expertise in speculative fiction. Craft a compelling story about a protagonist who possesses the rare ability to see glimpses of the future—but only through cracks in physical objects (e.g., walls, mirrors, or even the sky). The visions are fragmented and cryptic, forcing the protagonist to piece together clues to prevent impending disasters. [SETTING: a dystopian city on the brink of collapse], [CONFLICT: a shadowy organization seeks to exploit their power], and [TWIST: the cracks are spreading, revealing a parallel universe]. Develop rich character arcs, atmospheric tension, and a climactic resolution where the protagonist must choose between saving their world or crossing into another.
