Harry Potter and the Goblet of Fire is definitely a pivotal point in the series. The first 3 books managed to get by on the novelty of Harry joining the wizarding world, coupled with the fact his life becomes under an ever increasing threat. This hasn't been exhausted, but isn't enough on its own to sustain a forth book or indeed the rest of the series. JK Rowling appears well aware of this and decided to really expand not only Harry as a character, but also the world he operates in. This really allows the reader to be drawn into the fact we are observers in a world that is no less complicated than our own, and the dynamics within it are not black and white.
Harry begins the 4th years in dramatic fashion, a visit from the Weasley family doesn't quite go to plan, much to the dismay of the Dursley's, but this does not stop Harry from attending the Quidditch World Cup. For the first time Harry grasps the size of the wizarding world he is apart of, realising there must be many other schools all over the world to accommodate all the wizards that clearly must exist. Harry's enlightenment is short lived however, resulting in his trip being cut short, this though is forced to the back of Harry's mind as the elder male Weasley's are being delicately evasive with Harry, Ron and Hermione...
Harry returns to Hogwarts buoyed by his time at the Weasley's and just like everyone else at Hogwarts is instantly fascinated by the prospect of a replaying of an old school tournament played between the 3 greatest European Schools. Each school can only have one champion and to ensure fair play, the Goblet of Fire is used to big the entrants. Does someone have it in for Harry though?
This book really begins to highlight the strengths Harry is developing, highlighting his bravery and loyalty, whilst also showing that at times he is fallible, and when all said and done he is just a 14 year old boy...
The writing in this book is superb, the pace is spot on and although the book is lengthy you will race through it as if it was half the length. I really cannot give this book enough superlatives, the writing of JK Rowling has clearly improved and isn't as simplistic as the earlier books, maybe its because it's the middle book that this transformation has happened, or maybe it's just coincidence but whatever the reason, I am so glad it happened as this book really makes the series so far.
