Read all 7, and overall I thought it was a pretty good story. Yeah, he wrote himself into the last couple, but I can forgive that. I think it was his way of explaining that almost everything he's done and written over the years has somehow been related to this story. It's kind of a retirement speech, in a way. Though I have to say, I was a little disappointed in the ending of the last book (the second ending, not the first).
