The book sold 7.2 million copies throughout 2005 and its first day's sales totaling 4.1 million outsold other books' yearly totals. Meanwhile, a review of the audio version describes Stephen Fry's reading as "... captivating stuff in Fry's hands and he is terrific in the way he can convey the difference between the nastiness, say, of Draco Malfoy and the truly black evil of some of the death eaters."
