Book 7 has a surprising ending

“Deathly Hallows,” which runs to 784 pages in the ink-and-paper version, took about two and a half weeks, working six-and-a-half-hour days, recording about 18 to 20 pages an hour, to finish. As with the other books, Mr. Dale received the manuscript only two or three days before he was scheduled to begin recording. “That makes it impossible for me to actually read it before recording it,” said Mr. Dale, who does not possess the 13-year-old megafan’s ability to inhale the book in a weekend. So he read about 100 pages ahead, and noted all the different voices he needed for the first few days of recording. The benefit of reading in chunks, Mr. Dale said, is that: “I don’t ever know how the book is going to end so I can’t unconsciously lead you in the direction that the book is going. I don’t know who the villain is because I am just reading 100 pages at a time.”
