University, Bentley Little

U.C. Brea has never been a peaceful campus. But this term it's downright deadly. Violence, suicide, and so on are one the rise.

One teacher is approached by a crazed man who says the school is alive. While the teacher wants to write the guy off as a nut, soon he isn't so sure.

While I'm not sure I'll ever read it again, this was quite a disturbing novel.
