The name terrified Kai when he heard it on the news. The original supercomputer that he had built ten years ago was called the Whisper Grid. That machine had evolved and moved to the bottom of the ocean to become the Domain of Echo. Now, the public had taken that old, terrifying name and given it to the new, living economy. It was a sign that the ghosts of the past were waking up again. Kai walked through the central plaza of Crest City. The morning air was cool, but the atmosphere in the plaza was hot and strange. The Quiet Market was completely transformed. People were not smiling and sharing fresh bread. People were not fixing ovens for free. Instead, hundreds of citizens were standing in the middle of the red brick plaza. They were holding their cell phones and data pads up in the air. They were all playing the audio file at the same time. The deep, haunting melody of the market echoed from hundreds of tiny speakers, blending together into a massive, vibrating choir. Wooooo

The room was perfectly silent. Men and women fell to their knees on the marble floor. Some of them wept. Some of them stared at the wall with blank, empty eyes.

His voice was heavy with a dark, terrible truth. "A market is a tool that humans

The morning in Crest City was supposed to be quiet. The sun came up over the tall glass buildings. The sky was a pale, cold blue. People woke up in their beds. They drank their hot coffee. They got ready to walk to the Quiet Market to trade for fresh bread and clean water. But today, the city did not feel quiet. It felt strange. It felt like the air was buzzing with a secret electric charge. Elian, the young man who used to be a thief, walked down the stone street. He wore a simple brown jacket. He kept his hands in his pockets to stay warm. He looked up at the giant digital screens on the sides of the buildings. Usually, the screens were blank, or they showed beautiful pictures of nature to keep people calm. Today, the screens were different. Elian stopped walking. He stared at a massive screen above a clothing store. The screen showed a picture of a thick, warm winter coat. Next to the picture, there were words written in soft, glowing white letters.
