Yes, we have a review by My Little Pr0ny of Riddled by the Sphinx! I have to say check it out, but check out all of their reviews. They are hysterical, and I enjoy reading them a lot, which is why I'm usually up on when they review a new book of mine. :P
I wonder what they'll think of when they get up to Thunderstruck? It really did take a darker turn. I have to remember that the series is about pulp adventure and not SUPER SERIOUS SERIOUSNESS OF SERIOUS.
