Am joining the club of haters of the imprecise 'he' insertions. Never got a clue who is speaking or thinking what. This book is not superior in craft and not superior in story line. Not sure why this got any prices.
And changing time lines has to add value, to do it for the sake of it, is annoying to say the least. And quotation marks as well as commas at the right places seem to be a luxury these days.
