Green leaves rustled slightly in the breeze of a hidden vent unit far above her. In less than a month, the tree had doubled in size, and would soon be producing fruit. It was nothing short of a miracle, but for Sophie the sight was painful. The vibrant green of the leaves and crisp brown bark reminded her of what had been lost outside the safety of the Biosphere. It reminded her she would never again see lush forests or fields of crops. More than anything, it reminded her of the reason she was there in the Biosphere in the first place. The Earth had been dying for decades; the Organics were just finishing what her species had begun. Dr. Hoffman—the real Dr. Hoffman, not the monster from her dreams—had said that the Biospheres were humanity’s final hope. He had planted them across the world so that after the Organics had left, the human race could sprout and flourish again. Dr. Hoffman had made a fatal miscalculation.
