What Do You Need?

I'm reading Need by Joelle Charbonneau. Well, I'm not reading it right this second because I keep having to put it down. "Intense" may be too mild to describe this one. 

The premise is that there a new, invitation only, social networking site, open to only the students of one high school. The first few who join only have to get a few others to join in order to have their "Needs" met. Once all of the students join, they must complete tasks in order to have their need requests filled. And what's the harm? It's just a note shoved under someone's door. Just a false receipt created in a bakery.
It's just harmless pranks, right? And, really, some of those people being pranked deserve it.

Then the body count begins to rise.

Someone on an Amazon review commented that the premise is completely unrealistic-that no one would be stupid enough to do even the seemingly "little" things that the website asked. I beg to differ. Not I only do I know some teenagers who could be easily convinced to do some of the seemingly harmless activities, I know plenty of adults who would dive right in without asking questions. This is a frightening book. And the greatest fright lies in the fact that, for the most part, it is all too plausible.
