 The fourth book, Harry Potter and the Goblet of Fire, is published in both the United Kingdom and the United States, with a record-setting combined first printing of more than 5 million copies. This is the first time the book is released at the same time in both countries, and the first time it's released on Saturday, so that children can get and read the book as soon as it comes out without skipping school. Both these practices are followed for every book that follows.
This book is much longer (734 pages!) and darker than any of the previous books in the series, leading some critics to predict that the Harry Potter fad will end here. - July 23:
