If you want to get a good, reliable introduction to the 12-Steps from an Orthodox perspective, then I strongly recommend Steps of Transformation by Abbot Meletios Webber of St. John of Shanghai Monastery in Manton, CA.
Here is a review page for the book:
Fr. 'Mel' has a profound insight into the topic, and his book is absolutely an essential part of bridging the terminological gap between the Church and AA.
I've added a link to the book in the sidebar, which you can order from Conciliar Press.
