I read this book as part of a book club and I doubt I would have read it otherwise. The only other book I read about DPRK was [b:Dentro do Segredo|16167764|Dentro do Segredo|José Luís Peixoto|https://i.gr-assets.com/images/S/compressed.photo.goodreads.com/books/1353792467l/16167764._SY75_.jpg|22013273] and, even though I am interested in the topic and will probably keep reading about this mysterious country, I would have preferred to stick to factual books instead of fictional ones like Star of the North. Within fiction, there is always danger of giving way to prejudice and adding unrealistic details to real stories. That being said, I think D. B. John did a good job of laying out his sources in the end of the book and, therefore, I value the work he has done and I am happy to support it.
About the story itself, it started out a bit confusing due to the amount of characters but got better as I kept reading it. Some details were a bit unrealistic, specially when it came to the superhuman abilities of Jenna and Cho, but the book is enjoyable for those who are into action and espionage. I am not a fan of the writing style itself - too many adjectives, comparisons and metaphors. I would have preferred a cleaner prose to match the fast-paced plot.
