From the moment the letter arrived, Marcus was transformed. He whistled as he walked down the street, a tune he hadn’t hummed in years. He nearly ran into a street sign, lost in a reverie of possibilities. A half-brother, living in the same city!

He booked the best table at his favourite restaurant for the upcoming meeting, and spent the following days researching his brother. He was thrilled to learn they shared a love of baseball. He bought tickets to the next game and could barely contain his joy.

He picked up a phone and immediately called his mother, his voice thick with emotion. "Mom, you won't believe this…" He had a whole new family to welcome.
