Your thoughts on my story idea?

I think your plot is amazing, and I completely disagree with the other answer (ed bites, I think), you don't need to simplify it. If you want to make it a bit better then perhaps, when she is searching for Carson, she has to try and not get attached to the places she visits along the way, and maybe add a few love interests. I'm only 13 too and trying to write a novel as well, good luck with yours and hope i helped x
