Harry Potter and the Philosopher's Stone (Sorcerer's)--9
Harry Potter and the Chamber of Secrets--7
Harry Potter and the Prisoner of Azkaban--7
Harry Potter and the Goblet of Fire--6, but this counts the two times I listened to it all the way through on audio--so technically, it's 4.
My uncle has a hard time understanding how I'd EVER want to read them that many times...
He just doesn't know!!
