This is all about Murphy and we get a little insight into why he's like he is today. I just love the banter between Murphy and Potter it's hilarious and the usual shockers that we have come to expect in Tim's books. We see a different side to Murphy, pre slippers days and we meet Pen, love her she's such a great character. Then not to forget Seth who's always there twisting things up as usual and I just loved The Wizard of Oz theme.
