Monochromatic Nymph, I think you have a very interesting storyline there that has lot's of potential. But do be careful because age specific problems in stories can be sometimes hard to believe so make sure you have a rock solid reason for the creatures attacking only that age group. Other than that though it sounds good so far :yes:
Runic, That totally sounds like a good story. I think you should write it out, it would be perfect for NaNoWriMo. Even if you don't finish within the time limit you still would have started it and have the opprotunity to elaborate on it even deeper with out time resrtictions.
Heartrate Monitor, I read some examples of your writing and I have to say. You're very talented with words and if you were to enter NaNowriMo I bet your story would be one to be noticed by editors or publishing companies. I hope you do enter :yes:
