I have received this review from a friend who, two years ago, saw an earlier draft of Sable Shadow and The Presence.  At the time, he told me it was “boring”.  Needless to say, I have worked hard on it since.
Congratulations Bill! an outstanding achievement! I couldn’t put it down, meals no meals, I swallowed the book in two days. Your prose has become self assured.  You dominate it, rather  than being dominated by it. The research, as ever, is superb, and also completely open to being understood by the layman. 
I drank in the corporate politics, and the acquisition of Nano made me ”homesick” for my General Foods’ period in France. You have certainly managed to recreate life as it is lived – even to the pertinent introduction of the meta-physical element – though a bit wobbly in spots, it stands solid, protected by Sartre.
I like it (the meta-physical element) and feel close to it – I guess that’s one of the reasons why I think it such a  remarkable creation.  Your progressive development of style, skills and plot makes my mouth water for the goodies to come.  Thank you from me, but really from all your readers.
