I'm surprised no one has mentioned anything other than AA or (take what you need) AA.
I started in AA, did my 90 and 90, I was frustrated that there was no other literature other than the Big Book (and the supplemental AA literature which was based on it). I got some silly answers from my sponsor as to why *only* the Big Book was relevant to my sobriety (salvation).
In any case, I'm in SMART now, been for the last ~7 months. They have a very large recommended reading list of current books in publication. It makes a lot more sense to me to get a wide variety of research, perspectives, and approaches...and use those as tools rather than a single book, which is quite dated.
There are a number of secular sobriety programs out there, there should be a sticky at the top of this sub-forum, I think?
