Michael Connelly and Nora Roberts have the top two books, Fair Warning and Hideaway, respectively, on the Apple Books store's bestseller lists at the moment, but otherwise, the top 10 is pretty much Potters all the way down, with Pottermore Publishing's enhanced editions of J.K. Rowling's Harry Potter series occupying seven of the top 10 slots. At #10 is Robin DiAngelo's White Fragility, a timely entry during a time of civil unrest.
