Marc has lost everything, and he's simply waiting for the world to end, until he is accused of a murder? After the devastation and destruction, he is left with a small band of friends who help him. Now, Marc and the rest of the world are trapped by a virus that's killing everyone on earth except those ages 13 to 19 years old. With adults dying, it becomes a new world ruled by teens. Sound wonderful, right? Except, that a cure must be found fast, if one even exists. Otherwise, no babies will be born, since the virus has left everyone in the world unable to reproduce. To make matters worse, when you turn 20 years old, you die because that's when the virus is programmed to kill you. In this new world, only the strong survive, since mutated creatures struggle for power, trying desperately to annihilate everyone who stands in their way. Strange creatures emerge with preternatural strengths.
