See allI've read maybe a handful of books twice. And only one or two 3 times. I have read Ender's Game more than a dozen times (I've listened to the audiobook 2 or 3 times through). It is most definitely my favorite book of all time.
Update after 2023 re-read: This re-read was the first time that I felt the book wasn't a perfect 10/10. The book just doesn't hit the same way at 40 years old as it did when I was 10 or 20. It was still a very enjoyable book. Nobody writes characters quite like Card. He conveys and internal emotional life that maybe only Robert Charles Wilson and Robin Hobb can match.
