First things first, I like the way of starting the story of in a "cliffhanger". It sent me directly into the pace of action and mystery (good move).
Since it's a story of survival, it will be an interesting review.
"Reach Breach in memory"
The story sets off with a girl named "Bella" who found herself in a forest all alone, not knowing how did she get there. As the story progresses, "Vera" the voice inside her head appeared, which helped her to survive and motivate her to keep going.
What I have found interesting is that the "voice" inside her mind is mysterious... Is it really an unknown voice that she was born with? Was it an illness? Or is it a friend of the forest?
Towards the end of the first chapter, she stumbles upon a cabin of a "mid-fifty" year old fisherman. The fisherman seemed to know her name, but for an unknown reason, he didn't want to help her entirely.
One question that I asked myself while reading the first chapter, is, why did Bella run after the fox? What made her think it was a good idea (to run after her), or why was it a bad idea (to let her go)?
I saw the way that you've put a few words after the sentences, which I guess is to outline the dialogue for Bella? If that's the case, then it's original and well done.
*Some last things that I noticed, were the "repetition" of the words, I think that it could be the way that the voice of "Vera" is talking? (it would be interesting). The last thing would be the explaining of the events:
The way she panicked when a (simple?) storm was coming wasn't explained entirely.
When she walked for two days, how did she survive? What did she do two days, she kept walking? Did she eat anything or drink anything in that time, or her survival instincts made her continue?
Overall interesting start, and quite catchy, but be careful with when you introduce the dialogue, you could maybe outline it more to avoid confusion (I am not saying you should, but i would be safer, in a way).
