Freedom's Landing (A Freedom Novel Book 1)

The alien Catteni value strength and intelligence in their slaves—and Kristin has managed to survive her enslavement while hundreds of other humans have not. But her trial has just begun, for now she finds herself part of a massive experiment. The aliens have discovered a new world, and they have a simple way of finding out if it’s habitable: drop hundreds of slaves on the surface and see what happens.

If they survive, colonization can begin. If not, there are always more slaves.
