My sister was a girl in pigtails when she first killed a man. [I LIKE THE IMAGERY AND THE JUXTAPOSITION OF HER INNOCENCE AND MURDER. HOWEVER, I'M NOT A FAN OF OPENING WITH 'TO BE' VERBS, BUT THIS ONE ISN'T BAD.]

1) A lot of great details here. While the style is trying to stay simple/colloquial, the author has so heavily relied on the "to be" verb that it makes the voice not just passive, but bordering on dull. That seems like a waste when there's all this good material. Insert a few more active verbs and the reader would benefit. I crossed out all the boring verbs to challenge the author to come up with more intersting ones.
2) My hardest comment is that, despite the interesting material, the author has chosen to the dreaded backstory opening. Albeit really interesting backstory. If the 3rd paragraph cuts to current action, the author could probably get away with this. If not, there's a big problem. Debut authors can't get away with backstory as openers. It reeks of amature writing. Agents and editors complain that you should NEVER open with backstory. If you are not sure why, read the Query Shark blog or Janet Reid's blog. She pounds this message hard. We need to start a book in CURRENT ACTION/SCENE.
3) I forgot to mention that the author did a good job helping me care about people in this story, especially the narrator. He has simple needs -- wanting to read and write -- and has to watch his mama get displaced. Still don't know the POV character's name, though (boy or girl?). But to open with heart in your story is very difficult, and you've succeeded.
