Stephenie Meyer writes the dreams of teenage girls and that speaks to grown women. Just ask my female friends. It is because we are all still 14 at heart. We are all pretty much still that scared. embarrassed, awkward person we were in junior high school or high school until we become fearless. Most of us aren't or don't achieve that which is why these books/movies are a hit
I don't think she is alone in this. A lot of things capitolize on this thinking. Rom coms do it (and I love em) but everyone knows it's bs and it's not as stalkerish or weird as the weird teen fiction that is pushed by this.
I just think that what teenage girls like isnt healthy. That's why they have entire talk shows devoted to their poor decision making.
