This is where you'll find further reading on the world of Turning. If you haven't read the novella yet, I ask you to imagine you've stumbled, unarmed, into a dark room packed with zombies. It's just you, them, and the light bulb that swings from a cord between you, lighting up things you're not ready to see.
Now, slowly back out of the room, turn off that switch and quietly shut the door behind you. :)
Okay, okay, turn on the floodlights - there's nothing here yet.
