Crank guided response

The book "Crank" has me itching to want and read more of the book already, and im not even that far into it yet. The book is already filled with alot of sexual refrences and major drug abuse. The main cahracter is a girl named Kristina Georgia Snow. My first opinion of the girl is that she is crazy, just because of the simple fact that she goes by and alter ego. "Bree" is Kristinas alter ego and that is basically her "wild" or "bad" side. It seems that she basically hates her life and whenever things go bad or not her way she turns into "Bree". She tells the reader in the begining of the book that she basically no longer has no family and feels alone. Kristina also come off to me as a girl seeking attention because she does not like the way her life is. Kristina seems to be a typical teenage girl that hang around with the wrong people, because she wants to feel wanted or seeks attention.The bad decisions that Kristina Snow had mad will lead her to fall deeper and deeper for the monster or "Crank"
