Nothing was as it was supposed to be, and I was sick of everyone saying I'd die. My heart had been ripped out; I'd been stepped on; and I'd been underestimated for much too long. It was time to prove to everyone I was stronger than I looked. It was time to fight. I just didn't know if I could survive Tallis and the future that kept being promised to me.
