With many authors I always recommend grammar checking. Reading yours, I found that it was quite excellent and made the story flows really nicely. I thought the introduction of the character, Park, was really interesting and brilliantly done I might add. Overall very intriguing and highly recommend to everyone. It's not everyday you find a good novel of high quality, and this one definitely represents that. I have read many books, and never one quite like this.
