Demons exist. So, why shouldn't zombies?

They're fucking creepy as hell for one. For two, the damn things are attacking people in order to draw Kara out. 

A month ago Kara's life was, for the most part, pretty normal. Annoying ex, awesome best friend, asshole parents. She was just a normal teenager with an attitude problem (what teenager isn't?). Only shortly after nearly becoming a demon sacrifice, and with the help of her new demon boyfriends she finds out that she's not at all what she thought. She's more. She's special. And being special sure as shit isn't all that it's cracked up to be. Because, now there's a zombie army being made and they're coming for her.
