Nick Dunmore notices strange things happening. He sees a mysterious package that is being passed around at his school. Nicks initially thinks it is only a pirated CD, but after he gets his hands on it, he finds something much better: a computer game called Erebos. He discovers that the game is so addictive that it takes control over the gamers. The game connects with the real world, giving you seemingly mindless tasks to complete in order to level up.
Sloane and five other teens are trapped inside their high school during a zombie outbreak. Just one bite to kill you and reanimate you as a vicious creature without any sense of love, compassion, or remorse: only a hunger for human flesh. People have become erratic and sometimes Sloane doesn't know who to trust. The necessities of the group change drastically, everything turns for the worse, and their willingness to survive takes them to a new level.
