Her Superpower:

    Holly was the sort of girl who frightened people with silence. The sort who would wake up one day and decide she didn’t need you, and that would be it. No discussion. She had always been able to do this, just walk away. She managed somehow to convey this fact to everyone she met within a few minutes. It was an unsettling ability. People would be sitting with her, conversing, thinking that she was charming, in a dark way, and pretty, in a pale way, and suddenly the thought would creep in: I don’t think she’d ever need me.
