A Question of Intrigue

I've been writing a story that I hope someday to publish, but I'm having trouble deciding which of the three beginnings I've played around with is the best. What do you think?

1. "It all started in the most bizarre way I could have ever imagined. I was nothing back then, just the outcast girl who spent all her time immersed in books. I wouldn’t have minded if they had paid no attention to me, but the nickname “Factory Reject” was a bit hard to take. Nevertheless, I did my best to ignore the snide comments and jeering looks. That had been the state of things for my entire school career. By the time I entered fifth grade, I was convinced that nothing would ever change. The first sign of how wrong I was came on the very first day. Although it was most certainly September, the weather was still nice enough that the teacher left the windows open."

2. "My name is Rebekah. I am called Ninelives by some. My story is one that I would never have thought possible. Thinking back on the time before I found my true purpose, I see now that I never really believed that I would have the chance to become anything more than a pariah. I thought I was weak. That was the one thing that I was most wrong about."

3. "I didn't need to look behind me to know what was there. They were always there, the same menacing figures that followed me whenever I had anything, anything at all, that I valued. Seven years of living--more like surviving, really--like this had taught me to recognize this instinctual knowledge.

"Of course, since I couldn't really act on them, it didn't matter whether I had those instincts or not."
