Drop the Rock is a short, practical book aimed squarely at people working the AA Twelve Steps, focused specifically on Steps Six and Seven. Bill P. and his coauthors take the dense language of the Big Book and walk it through what it actually looks like to become entirely ready to have your defects of character removed.
The metaphor is simple. The rock is the resentment, the fear, the ego defense you’ve been carrying. The work is letting it go, which sounds easy and isn’t.
The writing is conversational. There are personal stories from people in recovery, lots of practical examples, and a tone that assumes the reader is doing the work rather than just reading about it.
For anyone in or around recovery programs, this is one of the most-recommended supplements to the Big Book. It does what it promises in roughly 100 pages.
