20 years after the first signs of zombies, Clair, found herself in the green department, otherwise known as modern day middle-class. There were different colonies, settlements of survivors. There was Red, Orange, Yellow, Green, Blue, Indigo, and Violet. Red being the settlement with the least amount of supplies, and Violet being the one where you had everything. Each settlement was protected with various cement walls and fences, to keep out the menacing, rotten, flesh eating zombies. One downside of having different settlements, placed very far away from each other was communication. The only way to communicate was to send people back and forth between the colonies, runners. The seven colonies were placed across what was America.
After Clair was tested and allowed in the green colony, she quickly became a runner. Running miles and miles a day, just to deliver messages between the colonies. With only one other person to travel with, will Clair live to see her own family again?
