I know the author a little and I know the publisher rather better; but what really flagged it up to me was
Knowing Conor’s politics I was wondering if or how he would manage to bring in the revolutionary overthrow of the system, and he does it through a combination of a young hero and his friends teaming up with older mentors (one the central character’s father, the other the ideological guide for the revolution). However he manages to keep the suspension of disbelief and (I would have thought) in a style attractive to the target readership. If you don’t want your teenagers exposed to insidious lefty propaganda, don’t let them read this book. On the other hand if you want them to be intellectually stimulated as well as entertained, you could do a heck of a lot worse.
