Sparky and his pals flee aboard a starship from a mining outpost on Saturn’s moon, Titan, as they help Electra escape the dreaded Earth Patrol and head for Mars, where Electra will find sanctuary. Their mission is to reach the planet Mars without encountering Ambassador Black, whose orders are to stop them at all costs take Electra back to Earth with him. During this 740-million-mile adventure to Mars, our heroes meet a host of odd characters – some good, some bad, and some most terrifying – including the teen Bobby Black, Ambassador Black’s nephew. Even though they are at odds with each other, Sparky and Bobby must learn to work together to help Electra reach Mars safely.
