However, I do feel that it was marked down on a point that was not entirely accurate:
". . . the absolute lack of any person in any form of authority being portrayed as a good or even decent person seems to take the conspiracy a bit far."
This is emphatically untrue. While questioning the validity of authority is a significant feature of Hold On!, not all authority figures are described as being malevolent. Characters such as Agent McKay, Officer Blaine, Director Wolfe, and Chief Tepper, are all illustrated as good guys. Moreover, only a handful of featured authority figures have any connection to the conspiracy. I don't know how all of this could have slipped below Ms. Bradley's radar.
In all though, it's a pretty good review that shows an understanding of the book's agenda.
