Even though I read this years ago, I love this series and I still remember the way this book ended the trilogy.  It's hilarious yet emotional.  I love the dry and ironic humor (I think it really shaped my own humor).  It's really interesting to see how all the characters changed over the course of the series.  While I don't remember a ton about the plot itself, I remember really enjoying it.  Bartimeous (can't spell his name) is one of the best fictional characters written, and I love the way his POVs are written.
