I don't quite know what to make of this book. I've been wavering between whether I don't like it, but it's well-written, or whether I do like it, because it seems an accurate representation of the dark side of human nature.
There are various grammar and punctuation mistakes, as well as missing words, in the book. Even so, I was able to read the book and it's given me a lot to think about. So I guess in that respect, it's done its job.
