Pursued by President Harker's secret agents, they piece together clues pointing to the existence of a galaxy-wide conspiracy. In need of help, the three kids track down legendary astronaut Gerald 'Fox' Fuller who has retired to a life of surfing and yelling at anyone who interrupts his surfing. When Fuller tells them the space shuttle on display at the science museum is fully operational and ready to launch, they know they must steal it and blast into orbit. Their mission: Destroy the military's orbital space weapon before Harker can deploy it against the peaceful aliens approaching earth. Heroism does not come easily to Infinity, Gabe, or Twilight. They feel big feelings but find a way to be brave, fight through it all, and triumph in the end.
