I like your head Sam. I too did NOT consider looking at either of these books as I have lived with alcoholism for 40 yrs. and doubt anyone can shed much light on the "why". It all still boils down to personal choice and giving outside influences credibility is against my religion (common sense). I will say this: If it helps someone stay sober for even 6 months, then it's good. No "beliefs" will conquer the whim but some can help.
