The saddest book I've read is "A Walk to Remember". It's about a guy who tells his past experience with a girl at the age of 50 something. The girl was a leukemia victim and the guy fell in love with her. He didn't really know it at first but then when he knew, he never left the girl. He did everything to make the girl happy because the doctor said she will not last long. But then, a time came when the girl had to go. The guy knew that her girlfriend's wish was to marry before she died. The guy married her despite the fact that the girl was dying. Isn't it just one of the most romantic stories you've ever heard?
