Refreshing and necessary elaboration on experience-based approaches over the traditional 'alcoholism-is-a-disease' approach of AA.
For those looking for alternatives to the AA belief that, among other things, there is something inherently wrong with us, it is a constructive and useful realization here that perhaps, given some behavioral advice and practice toward sobriety, we might learn to rely on ourselves for better choices and and outcomes.
The first few chapters are a well thought out, concise tour through the psychology of recovery, focused on evidence-based, common-sense aspects of our behavior. Very valuable to the beginner.
For those in recovery for some time, its later detail and methodical nature might be of particular value to those in cbt or dbt approaches to recovery. It's VERY detailed -- once over that you'll find it very readable as a second or third text on the subject.
Very valuable. Seek it out. I got a LOT out of it I found useful.
And good luck!
