OK sales for Rowling's new novelSales for J.K. Rowling's first adult novel were hardly magical during its first six days. But the publisher isn't complaining, The Associated Press reports. Little, Brown and Co. announced Wednesday that "The Casual Vacancy" has sold 375,000 copies so far, a figure that includes hardcovers, e-books and audio books. That makes Rowling's novel among the fastest-selling new releases of the year, although not in the same league as her Potter books. The last Potter book, "Harry Potter and the Deathly Hallows," came out in 2007 and sold more than 8 million copies in the United States alone in its first 24 hours.
