When the Stone twins made up their minds to leave Lunar City in a secondhand spaceship, they hadn't planned on having their whole family accompany them. But the Stones were not your ordinary Lunar family no way! and their voyage through the solar system sure proved it.
What began as a simple business expedition to Mars soon mushroomed into a dangerous situation when Grandma Stone was lost in space. Then, just when everything seemed to be getting better, a Martian flatcat came aboard and fouled up the works.
But the real trouble didn't get underway until the Stones headed for the asteroid belt to take up a mining proposition they, somehow, couldn't refuse . . .
