There was a list posted on the site Imgur a while back, entitled: SINK YOUR TEETH INTO HORROR. It mentions loads of interesting-sounding horror books for adults and YA, handily broken down into categories such as "Zombies," "Vampires," "Demons" and so on. The Demonata got a nod, which was nice. There was no mention of Cirque Du Freak or Zom-B, but hey, you guys know about those already, right?!? But I bet there's plenty here that you DON'T know about, so if you want to broaden your horror field considerably, click on the following link for more recommendations than you can throw a headless horseman at!!!!
