The author clearly has an in-depth knowledge to how multiple parties behave in times of conflict, and that's where the book shines. I'm not surprised as the author is a journalist with a history reporting on conflict.
I found his writing style to be patchy and his use of symbolism a little heavy-handed. Also, I thought the framing device seemed a little odd as it opens as a first person narrative for a few pages and then switches to third person for the vast majority of the book. I think it would have been stronger if they'd left it all in the third person as the first person components don't seem to gel with the rest of the book.
That being said, it's a quick, easy, engaging read and as I mentioned earlier, the attention to detail when describing the origins and implications of conflict was strong.
