Mona nodded quickly to her sister's question. Yes, she'd told their parents she was going to find Maddy wherever she was, but they had thought it was a thing she'd never manage to actually do. When the voice had told Mona to come to Detroit she'd thought of nothing but getting there, and so it was only when the plane landed in Michigan that she called to tell them where she was and what she was doing.
"I'm here forever," she told Maddy seriously, needing to make her understand how firmly she felt about this. Mona had always been stubborn and determined. "I've come to be with you in this place. I'm not leaving."
