Thanks very much for your comments on this. I appreciate what everyone has said, and that it may be difficult to convince anyone to read it because of the depth of indoctrination, but still it's worth a shot. The family members I have in mind wouldn't shun me over it, and they may read it if I point out that there is nothing current naming the book specifically to be avoided, and if they think JW's have 'the truth', and the GB is divinely inspired, one would would hope they have some interest in knowing why the guy who wrote the Aid Book (which my dad still sometimes uses!) would jump ship, especially when he was on the divinely inspired GB.
Of course I will have to work on my sales pitch and I will read the book myself first!
Does anyone know of any other society publications written by Ray?
