 What did Mia have for siblings?
The ancient rule was sink or swim—swim in the miasma of a planet without spaceflight, or sink to utter destruction! I The horses and packs were loaded before we went aboard the scoutship. They don't let us grow for fourteen years and then kick us out to die. Considering how short a time it was in which the colonies were established, there was not time to set up industry, so they had to have draft animals. One of the eight, as well as the two that were being built then, went up with everything else in the Solar System in 2041. I don't know how many of those planets had animals that could have been substituted but, even if they had, they would have had to be domesticated from scratch.
