A book written by Stephenie Meyer, about a vampire who falls in love with a human.
And well yeah thats it, oh plus the fact it is slightly sexist as Bella goes into depression when Edward leaves her, and when Edward comes back she falls to his feet. It shows quite a weak image of women, especially when they are in love.
Of course this is Stephenie Meyer's book so she can write whatever the hell she wants, and it seems to be doing pretty well.
Second book in the Twilight series... Bella trys to kill herself when Edward leaves her.
