It's not the last one. Five's out, six is coming out in November, that's a single chapter, and then seven is the big horrifying one. And I think a couple after that to wrap the thing up.
Of course there are certain things that get to me, but I try and lead by example and show people that, especially with haters, that you should just ignore them.
Reading 'Moby-Dick' was really a sort of transformative literary experience for me.
