For a book to be labeled a "mystery," shouldn't there be some sort of mystery that needs to be solved? Even if it's just some guy in a mask scaring kids away from a lake to look for gold? Not to mention that the ease with which the "spy" goes about her business would make James Bond look inept. This book is sorely lacking in suspense, drama, mystery, romance, or credibility. It makes me wonder if the target audience is supposed to be adults or the young adult audience the previous series is supposedly aimed at.
