One of my newer novels:

Ella Morris, a fifteen-year-old at Mason Hillside Academy, is anything but popular. All her life, all she wanted to do was make it a little bit higher on the social food chain. At least she has Sylvia and Joanie to help her back up when she falls on her butt. Starting tenth grade wasn't actually as bad as Ella thought. Then soon after the MHA Halloween Bash, two girls end up missing and soon found hanging in the girl's bathroom a week later. Everyone tries to rid this from their heads, but the memory of seeing the two helpless girls hanging there keep coming back to haunt them. About three days after the two girls were found, two more went missing. The numbers kept growing as the students keep dying. After Ella returns home from a party to find her parents crying, she discovers that her own little brother, Alex, had been kidnaped. Ella decided that then and there, that she wouldn't let the same fate happen to Alex. But first, how to catch a murderer?

Spooky huh?

Okay, if this seems too like a cliche horror/mystery novel, tell me. But, it's a start... Right?
