Dead Trigger (Highschool of the Dead fan fic)

A normal highschool, full of normal kids, and anything normal. Until that is, when a disease turns people into the undead, only passed on by biting others. There is one group at this school, which survives. The dead rises, and they must survive. The world they once knew, is gone, but to be replaced by people, dead, walking, and turning others into, "them". Will the group survive?
