Query: Harry Potter.. The worldwide obsession.

The latest and second-to-last installment in the Harry Potter Series is a good one.The book seems confusing in the beginning, with new names, characters, and situations, but quickly gets back in the classic Harry Potter milieu. J.K. Rowling works her magic of words again, spinning a tale with as much depth as you'd like to perceive.This is an excellent read, and one of my favorites in the series.
