When I was reading these to my son, I took a break after POA. I had read them before and knew I should wait until he was a little older to keep going. There is definitely a feeling of a cliff at the end of POA — stuff about to get serious. I agree about POA and the detail about the school and culture. I also love it because it introduces use to the previous genderation is such a more detailed way. The clothes really are an issue.
