What do you think of Chapter Four (so far) of my story?

Wow, your story sounds really good. The only thing that I would suggest to improve is to make Amber not make so many exclamations. I guess it does make sense though, seeing as she's locked in a cage and all, but still I would suggest to maybe cut out, "We can (line 36)" and have her only say, "I know we can!" And also on line 42 to have her say "I'll kill you," rather than "I will kill you."
