I am a slow reader by choice.
I like to take my time with a book especially when it is well crafted and beautiful.
McCarthy's 'The Road' took some time - although it is not a big read and the comments on the cover suggested that it may (and should) be read in one session - I did the opposite and read two or three pages each night over the last few weeks.
Why does this book resonate?
At one level it could be described as bleak, lacking in plot and gruesome.
But there is something captured here that is difficult to describe and yet powerfully familiar.
It may be that this novel somehow connects with our collective unconscious and reveals a stark truth about existence.
Can't really work it out ... no need just let it be.
