Just like that, J.K. Rowling has “wingardium leviosa”-d her way right back to the top of the bestsellers list. Moving 375,000 copies in its first six days, The Casual Vacancy, Rowling’s first adult novel, tops USA Today’s bestseller list. Little, Brown, Rowling’s publisher, says the book is “on track to become the year’s best-selling in hardcover.” The Casual Vacancy bumps the popular erotic novel Fifty Shades of Grey off the top of the list, where it has reigned for 21 of the last 23 weeks.
