The house was quiet, the only sound the gentle hum of the refrigerator. Leo sat at the kitchen table, scrolling through his emails. He'd been expecting news for weeks. This was it. The wait was over. He had to be calm.

He found it, buried deep in his inbox. He opened the link, feeling a familiar lightness fill his chest. It was there. His article.

He scanned the text, marveling at the words. He found the byline, and froze. He didn’t know the name. This wasn’t right. He almost felt the need to laugh. He took a sip of his water, and scrolled down.

He could fix this. The world would know his name, and his ideas. For now, he just had to enjoy the moment.
