Who is James Frey from A Million Little Pieces and what is their importance?

Author, narrator, and main character of this memoir, James Frey is an alcoholic and drug addict who undergoes treatment at a rehab Clinic in Minnesota. He relies heavily on his own strength in order to get through recovery, as opposed to using the AA-sanctioned twelve steps. James has a severe aversion to authority figures of all kinds, including his parents, God, administrators, and even his addiction. He refuses to believe that his addiction has power over him.
