Nanoagents: Mars Rover

In 2010, the Mars Rover named "Spirit" had stopped sending signals back to NASA. In 2011, NASA ceased all efforts to communicate with the rover and called the mission complete. But something unexpected happened: Spirit started to send signals again. The weird thing was that the signal was nothing that Spirit had been programmed to send. It was as if something or someone had taken over the rover. The Nanoagents have been tasked to figure out what's going on. But how will they get to Mars? And when they get there, what are they going to find? Seth, Ajita, Jaden, Cheryl, Chen, Bits, and Rez will have to work together through node networks, forcefields, mechs, and battle drones if they're to succeed in learning the secret behind why the Mars Rover Spirit has come back online. Will they even survive?
