Astrid Maxxim and her Amazing Hoverbike  is available now at Barnes and Noble for the Nook.  It’s designed for readers of middle-school age, and is just 99 cents.

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?
