I don't remember anything from "slaughter house five" I read two years ago, except that it made an impression at the end, and that it was a quality work. On the other hand, I can't remember the title of one book I read eight years ago, but vividly remember what it was about, and can recall one character's name. I can almost put myself in that book, and run it in my head like a movie. Few books I read stand out like that; everything else is forgotten. How is your memory with regard to books?
