“A sister?” Mark repeated, the word hanging in the air. He'd always envisioned a life of solitude, preferring it to the messy complications of family. The news – a half-sister he never knew existed – shifted something within him. He was drawn to the thought of her.

He pulled up her profile on social media, hesitant. He looked at her pictures, and felt a strange warmth spread throughout his body. He sent a message. Within minutes, a reply. An invitation to meet. He agreed to it, and he grinned when he did.
