The world was hit by an unknown virus two years ago. My family was sent to what people call "The Wall." However, I was part of an experiment when the virus hit us with four different variants, and one caused the living to come back from the dead. Dead who are fast, light, and unknown to us can sign, and some can speak and write. To my knowledge, my group was the only experiment. The experiment was kept a secret but was leaked by somebody inside. Those who were in the investigation could go to the wall. I took my brother and cousin before the world went to shit. When I wanted to end it all, I got off the roof and went to my self-defense class. This takes us to now—a twenty-year-old with a six-year-old. Then when the world went to shit, she called an old friend. Follow the journey of Alex, the only living experiment, and Nelson, the youngest of the group, as he finds new stuff every day. And Vicky is the last person to join the group as they find a way to keep each other safe and stay by each other's side as they have help along the way.
