They say what does not kill you makes you stronger. If that is the case, the MC must be one of the strongest men on earth. I will warn you right now, there is a lot of darkness in this story. At a couple points, I had to put my Kindle down and stop reading for a while, not because the scenes were unrealistic, but rather because they were possibly too realistic, and very disturbing. If I could have, I would have crawled into the story and ended some people who richly deserved to die.
For a plot score, I give it an A (8). Are there a few holes in the plot? Perhaps, but it does a good job of fleshing out more than a decade in the life of the MC, skimming over points that did not add to the story and delving into greater detail when needed. One life lesson? Don't let revenge steal away your humanity and your life in the process.
At the beginning of the story, the author apologizes for any mistakes in grammar and such, as he is Finnish and English is not his mother tongue. He must have gone back and made quite a few corrections. The story still needs a good editor to go back through and fix the remaining items, however. For technical quality, I give it a C (6).
For appeal, I give it a B (7). This was a very well told story, don't get me wrong. The main problem I have with it is that I would never want to read it more than once, only because the story holds so much of humanity's darkness and exposes it. My heart hurts when I think of any of what happened to the MC happening to anyone at all, let alone starting with a teenager and then going on for years because he can't escape the area. If I heard of something similar happening in real life, I would be too tempted to go and right some wrongs permanently, and that would put me in jail. Best to drive that darkness out, or bury it very deep.
