Aspiring wizards, start your broomsticks! Harry Potter and the Order of the Phoenix, the long-awaited fifth book in the kid wizard series, arrives in bookstores at midnight tonight amid very enthusiastic reviews. "It was worth the wait," raves The Associated Press, a sentiment shared by USA Today. "The book richly deserves the hype." Meanwhile, author J.K. Rowling is already hard at work on the sixth novel, Scholastic confirms. She hasn't been given a deadline, which means it will likely hit stores in early 2019.
