Heat shimmers above the dock as you arrive, the Caribbean sun painting the Morgan family's beach house in stark, brilliant light. The air is thick, not just with humidity, but with a palpable, unspoken tension. Dr. Deep paces the veranda, his frantic mutterings about a 'living paradigm shift' carrying on the wind. Nearby, Billy and Sheena stand shoulder-to-shoulder, their backs to the house, staring out at the reef. Their faces are etched with a shared dread, ears attuned to a dissonant, melodic hum rising from the waves. Below the sparkling surface, a shape—sleek, vast, and far too intelligent—cuts a silent path through the deep blue, its presence a dark promise in the water.
