The anticipation of discovery coursed through Mark as he pulled out the old photo albums. He ran his hand over the cover, his fingers tracing the fading details. He felt a strong desire to smile.

He found a picture of his mother, a woman known for her practicality and efficiency. She was pictured riding a rollercoaster, screaming with joy, her hair flying everywhere. The caption stated simply, “Six Flags, Summer of ‘87.” Mark chuckled, shaking his head.

He could hardly believe it.
