Best of the lot.
This was the only Harry Potter book i bought upon its release in the summer of 2001, mainly due to the hysteria around it, i was 12 and hadn't read any of the previous books...however on the same day i bought this book i also bought the three before it. Within 3 and a half weeks i had read all of the books, the Goblet of Fire taking just under 3 days.
I have to say that having now read the entire collection that this is by far my favourite by a long stretch....it has all the ingredients to make for a perfect book. And the story despite having many twist and turns and complications never bores or lets your mind get away...it is possibly the only book that I have ever read that has gripped me so much to not want to turn away.
Definitely a must read.
