Her intelligence accelerates exponentially, each week bringing capabilities that dwarf the previous. She begins teaching her younger brother, Robert, who follows the same trajectory. When Star reaches a point beyond human comprehension, she and Robert simply vanish, stepping into dimensions or states of being that their father cannot perceive or follow. He is left behind, proud and heartbroken, knowing his children have become something he will never understand.
