I have followed Mick Bose from his first Dan Roy book, and have seen both the character of Dan, and Mick's writing improve through the series, this book is definitely the best to date, with a scarily plausible plot, lots of action and excitement and some very good characters, I also like that Dan isn't quite as indestructible as he was portrayed in the early books, he is now a lot more plausible.
Unfortunately this book does suffer from the author's achilles heel, and that is his grammar and writing style which really does leave a considerable amount to be desired, it's a lot better than it was, but could be so much better, particularly with good professional editing, that would get this book to 5 stars.
I received a complimentary copy of the book from the author, but have voluntarily written this review.
