Rogan starts off as kind of a jerk, which is not all that surprising considering how preoccupied his parents are. He attends Steve Jobs Middle School, which is also online, so has had very little actual social interaction in his life that is not virtual. Dealing with actual people is much harder! He does learn to work with his teammates and starts to realize the benefits of collaboration.
Calum and his Atomic Frontier corporation seem legitimate at the beginning, but the slowly emerging Ender's Game quality of his organization is chillingly revealed. Of course, only twelve-year-olds can save the world, and the five best candidates are those who excel at video games. Makes complete sense, right? This is the best kind of escapist fantasy for tween readers who believe that if the video game plan doesn't work out, surely their back up of playing professional basketball will!
There is room for a sequel, and I would love to see Mr. Reedy (Stealing Air, Words in the Dust) put his writing talents to work on more of Rogan's adventures.
