The entertainment value is great, judging by the twilight phenomenon! I would say that the story deals with many themes that touch the heart of youths and even some adults. After all, who would not want a story of selfless love? Also who does not want to read about mysterious things in a world that may seem so mundane and predictable. There is also a fascination with vampires and the supernatural. It is just a part of American culture. Finally, the style of writing is not great, but popular. Hence, it connects with the people.
