OR Books you wish you haven't re-read.
Sometimes you read again a book and enjoy it as much as the first time, or even more. But others...
In my case, it happened with the Foundation Trilogy (Isaac Asimov). I loved it when I read it, but when I had a look again, I was sort of dissapointed. In my memory it had a special aura I didn't find again. I wish I didn't re-read it.
