I started reading this because the other book I was reading was kind of boring me, but this one was even worse! It's a wonder I actually finished it.
My first problem with it was that it was new adult romance. The heroine was largely forgettable, though she was quick witted. I hated how much she bed hopped and was fairly proud of that fact. I couldn't understand who her "brother" was, and what the conspiracy was surrounding her. It never gets fully explained, either. She breaks the "major rule" and yet winds up a Hero anyway, continuing on with missions. The book was too vague to make sense!
All in all, this was largely forgettable, and I'm abandoning the series and deleting it from my Kindle.
