Ethan Oster is a normal kid, until one day his life is thrown into chaos when a nuclear event happens. Thousands wiped out, hundreds killed, mutant zombies, and powers-- powers activated in a certain bloodtype, one that scientists call): Type R-3. The powers are dormant in those who have the blood type, but the nuclear event triggered the blood, causing the abilities to become active. Now Ethan must survive with his brothers, friends, and boyfriend, and find a way to stop the nuclear event... or at least not die.
