A familiar plot, reminiscent of a film Edge of Tomorrow mixed with a generic Korean gangster/cop genre and finally X-men, or any sort that deals with the fear of the unknown other and the violence that is implicated from it. A story arc told from viewpoints of multiple characters, with a de facto main being a strong and compassionate woman.
The book reads okay in that it's an interesting take - a Korean spin - on a familiar story. On the downside, it's exhaustively written, or it reads belabored, not in a Kafkaesque sense but what I believe is from insufficient editing. Also very violent to the point that violence becomes meaningless. Lastly, the villain is not at all interesting. I skimmed through some parts throughout where I felt are superfluous or too familiar.
On a separate note, I'm not having luck in my choice of books as of late. Sigh.
