Alright, I'll give you a little feedback on Unbroken:
The story's good, the central character is well-written and psychologically sophisticated, but the prose is a little 'chunky', which is honestly entirely within character if it's literally the main character's own writing (As a middle to high schooler), but could possibly be refined to come off a little cleaner. An example:
"But there was no way she did not hear my cries in the night. But I never spoke to her about it" (opening two sentences in a row with 'but' in this context doesn't seem completely right). That being said, the contents of the text are often pretty good, with regards to the figures of speech or the specific things the character writes about.
Ultimately, the chunkiness in the prose is small enough to be possibly a conscious decision, but it's big enough to maybe have a little of a tough time holding the attention of some people. That being said, I can't stress what I say next enough: Don't just change it for the sake of making it easier to read. Go with whatever your artistic vision is, whether that means keeping it the way it is or cleaning it up slightly for flow tweaking and ease of emotional resonance or whatever.
Overall, you probably already knew this, but I really dig what you're doing here. You achieve in painting the picture of this girl's life without bogging us down with insignificant little details, which is more than I can say for some of my own first draft content.
