I love this topic!
Okay, these are the first and last lines for the novel I'm currently rewriting:
Beginning (the rewrite): As I pushed my bike through the street, a girl came up beside me, heading in the same direction as I was. She looked about five with short brown hair and bangs that clouded her eyes. I wondered what a girl so young was doing alone, walking such busy streets at an early time. “Does your mom know where you are?” I asked her as we turned a corner.
She didn’t look at me, and I felt kind of relieved. She wasn’t my problem and her lack of attention to me made that clear. But then she said, “We’re coming,” and my relief fell.
Ending (the original): And I hate you too, Bavol. For choosing to disrupt my life and spinning it into a circle of misery, then not helping me the only time I needed it. I hate you just as much as I hate Iskinder and Brahanu.
You’re all the same to me now.
Yes, by the end of it she does have a lot of anger. That's all for the next book, though.
