The world is a dangerous place. School shootings happen nearly weekly. Bombings happen with frightening frequency. Then came that fateful day, the day that changes everything...on March 28th, 17 elementary schools were targeted and 10,000 children died in horrific bombings, more died in the days to come from their injuries. From that point on, people begin to turn inward and kept on turning. Maddie was 5 when the bombing happened; she's now 17 and very rarely goes outside. She attends digital school, socializes online, shops online. The only time she gets out of the house is to play soccer. She wants something different but doesn't know how to get it until she meets the mysterious Justin. He awakens her to the real world, the one outside of her computer screen. It's terrifying and exhilarating, all at once, and now that she's gotten a taste of it, she's not sure she can go back to her small room, her father who tracks her every move, her mother who seems to want more but can't get it. Escape is the only option.
