Edward hasn't discovered 'vegetarianism.'   Bella's out alone in the woods and Edward attacks. Alice has had visions of Edward joining the Cullen's for months and has to race to stop him killing the one person that could turn his life around. As Edward helps Bella recover he has to decide the answer to one of the hardest questions he's ever had to ask himself. What is more tempting, her blood or her body?

"Good." He paused, and took a deep breath. "Now, stories, fairy tales if you will, teach you things. They teach you to dream, to experience a world outside of your own. To escape from reality. But, such fantasies must have origins, don't you think? No one person could have such a vivid imagination to create a world so differently than our own. They must have known that some of these tales or elements of them, existed in reality. Us, my family and I, along with many others, are indeed characters from such tales. Monsters in most," he said in disgust. I, personally, couldn't imagine a world where Carlisle or Alice could be classed as monsters; they were too beautiful, too gentle to be worthy of that description. "We are what some call the 'Cold Ones'. Others know us as the 'Danag', the 'Estrie', the 'Upier', 'Varacolaci', 'Nelapsi', 'Stregoni Benefici'. I could go on forever. Lies have been spun and names created, but you would probably recognize us by the more widely known name." I had become so entranced by his story that it shocked me back into the present when he paused. I waited, with bated breath for him to continue. He looked deep into my eyes as if he was searching for something. "Vampire," he said simply. ~ Excerpt from Chapter Three 'Collision Course'

Told from both Alice and Bella's point of view for the first two chapters, but after that, it's all Bella.
