It's too hot to trot

Have you ever started to read a novel that you enjoyed so much that you started feeling sad half way through because you knew it was going to end in just a few hundred pages, and the story that had become such a part of your life would be over, and the characters at once so real would soon cease to exist, but you wanted them to continue being real, and you wanted to be part of their world, to share their experiences, and be like them, and act like them, and you wanted the novel, and their life, to go on forever?
