But I don't know how she's going to make Edward and a rational Bella stay together. Seems like it would make for a short story. "He's a distant, socially-reclusive vampire who says he's dangerous and bad for me? Okay. Next!"

That's what I originally thought. But closely reading Midnight Sun gave me the material to faithfully render Edward, while changing enough as a direct consequence of Bella's revised personality that her choosing him wasn't insane. (Or at least I think I've managed that.)
