I found this book unreadable and had to give up on it; most unusual. The complete point of the book escapes me as it meanders from one thing to another without coherence. I have to agree with "a keen runner" that the book was boring and above all the choice of vocabluary extraordinarily irksome. It is written in a relaxed laconic style that perhaps does not cross the Atlantic well. If it is an attempt to be vivid then it fails. I don't have the expertise of "Gerund" but this review seems to be spot on.
My advice, don't waste your time on this. I have no idea at all why it get so many rave reviews as it merits none!
