Pia hadn't quite caught the breath she had lost when officials from Nadar arrived on Martha's Vineyard and told her something she never thought she would hear: her sister had been found. Petra was alive.
She couldn't believe it. Her big sister was alive. The girl who had taught her to ride a bike, to catch lightening bugs, how to climb a tree... she was alive. Most of Pia's happy childhood memories involved Petra. All the memories after her were twinged by sadness, and most of them weren't worth remembering, anyway. She'd spent years feeling that part of her was missing; the sisters were just over a year apart, and she'd followed Petra around religiously as a child.
In the years Petra had been gone Pia had gone through a million emotions. Sadness, guilt, resentment, agony. But now none of that mattered. Now she was back.
The trip to Nadar and the walk to the estate, and then to Petra's room, was a blur. The overloridian had said something to Pia as she walked her through the halls, but Pia couldn't pay attention.
And now here she was, with only a door separating her from someone she'd spent her entire life missing/resenting/loving. She let herself in, and somehow found the courage to say, "Petra?"
