A Million Little Pieces- Summary so far

I just started reading the book A million Little Pieces by James Frey. The setting of the book is in a  drug and alcohol rehabilitation center in Minnesota. The Main Character, James is admited by his family after he overdoses and almost dies. James is seriously addicted to alcohol and hardcore drugs and he has been ever since he was 14. They try to help him get better but with his bad attitude and grudge held against the AA program he's not getting anywhere. Even though it's against the rules to say anything except hello to the female patients James finds himself falling for Lilly. James finally lets Lilly into his life and tells her about what he's gone through to make him end up here and she does the same. The book so far is mainly about James struggle to overcome his addiction and finally be able to look himself in the eyes.
