The lawyer's phone call had been dry, clinical. The information, however, was anything but. Samuel, a man who generally kept his emotions tightly reined, felt a jolt of something akin to euphoria. A sister! He had a sister, someone to share blood with, someone new to love.

He grinned, a genuine, wide grin that spread across his face. He found himself picking up the phone and calling his father, the man who had kept this secret for so long.

He spent the next few hours walking around town, a lightness in his step. He had a sister, and he couldn’t stop thinking about meeting her. He'd never felt so ready for a surprise.
