Kristin Bjornsen lived a normal life, right up until the day the spaceships floated into view above Denver. As human slaves were herded into the maw of a massive vessel, Kristin realized her normal life was over and her fight for freedom was just beginning…

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.
