The author was a woman too, and obviously writing for other women. And she knew her audience well.
Meanwhile, men did not care for Twilight. Which is to be expected, since it was not made for us. But the reason I bring this up is to demonstrate that it is not "the patriarchy" or any males who are responsible for the creation or popularity of this series among females. They chose to read and watch it, and any males who also watched were either gay or watched with their girlfriends.
