Freedom's Ransom [With Earbuds]

When Kris Bjornsen and her fellow slaves were dumped on an uninhabited planet by the alien overlords called Catteni, there was no guarantee they would survive. Without the help of Zainal, a renegade Catteni exiled by his own people, they might all have been food for the predators of the new world. But they did survive, building a civilization and a home on the planet they named Botany. In time they were instrumental in driving the Catteni away from Earth and neighboring planets. Botany is free now, and so is the devastated Earth.
