617-year-old superhero Jupiter Jet has kept Olympic Heights safe for the last year. Her flying skills are unmatched, and the city loves her. But she wants to do more.

Jupiter Jet yearns to soar across the solar system! Liberating the human race from the clutches of The Praetors, the aliens that imprisoned them. Not even her little brother's discovery of a long-forgotten radio can change her mind.

When the mysterious Black Flyer arrives in orbit and threatens her world, Jupiter Jet finds out that her "hero skills" may not be up to the task. Being a hero requires more than just a jetpack. Does Jupiter Jet have the courage to save her entire planet? We'll soon find out in the second volume of the Ringo Award-nominated series by writers Jason Inman and Ashley Victoria Robinson and artist Ben Matsuya.
