What starts out as a travel adventure story quickly turns into familiar Matthew Reilly territory; trying to trump one action scene with the next action scene. It is, essentially, a hero's journey story for kids. The author's notes/interview at the end of the book pretty much covers anything I would say. I'm really happy I read it.
Will I be buying any more e-books?
That really depends on Matthew Reilly. I'm really looking forward to whatever comes next out of that man.
