No Cure

Tessa and Justin met in a camp when they were children. They were isolated from the rest of the world due to infection. The world was masked with a virus and no one knew how it was spread. The world was eventually taken over by this virus and knocked the population down by 50% or more. Those who were infected eventually lost control of their body and became walking corpses with the appetite for human flesh. Tessa and Justin escaped the camp they met in and continued their journey throughout the years. They fight for their life nearly everyday but just keep moving. Is there a way to stop all of this and return to a normal society? I guess you'll have to read to find out.
