From the 180,000 acre campus of Maxxim Industries, fourteen year old girl genius and inventor Astrid Maxxim works alongside her father, Dr. Roger Maxxim, on projects to make the world a better place. Her latest invention is a flying scooter—the hoverbike. Is it the target of an international spy ring, or are they after secret Project RG-7, or Astrid herself? Astrid has something bigger on her mind though—high school. There's a field trip coming, and the Spring Fling is right around the corner… And does Toby like her as much as she likes him?
