It took me almost three months to read (I am not an economist, and needed some rest days).
The message that came over clearly (to me, at any rate) is that (a) the r > g thing will cause greater and greater inequality; (b) that Piketty offers a possible solution that seems to him the most effective; and (c) that his great fear is that if nothing is done, it will end in violent social upheaval, which is no-one's interest.
