Survival of the fittest (A One Direction,TWD, and TVD zombie apocalypse story)

One Direction. The boy band that stole the hearts of girls around the world. But what happens when they have to trade their popstar lives for one which they literally have to fight the undead to stay alive? Will they survive on their own or will they find help and comfort in both human and supernatural strangers? Please note: Ideas are from the Walking Dead One Direction world and Vampire Diaries television series. Characters included. I will try to update as much as I can. Comment on how you would like to see the story turn out. Your ideas might just get incorporated in!  Walking Dead characters and Vampire Diaries characters will appear in later chapters. The POVs in the beginning will mostly be in Harry and Zayn's, but as the story progresses, the POVs will change too.
