I might look in to Demonata, from the preview I read in the Darren Shan books it seems to be interesting. Also Animorphs is pretty good (but it's not horror, and I forget the authors name). I love anything written by R.L. Stine. The Fear Street series is absolutely brilliant! The spinoffs of Fear Street are also epic (like Fear Street sagas, which goes back to when Simon Fear was alive), but they are a little too gorey for my taste.
