Stephanie West - 2016

There were hundreds of aliens gathered for the auction, and these creatures were the largest yet. Their flesh was red like some kind of demon might be, with hair a uniform dark black. From what Giselle could see their eyes were a stone cold obsidian hue. Giselle noticed the fearsome creatures had long tails that rose out from what looked like chain mail kilts. Giselle shrunk back when she saw the creatures also had sharp fangs. How in the hell could she get out of this and if she did how could she possibly survive on an alien planet? Kagan beheld his pet. Nothing like her kind had ever set foot on Cadi. Kagan wondered where in the universe her unique species hailed from.

But something more valuable than precious metal or jewels would be lost if Giselle was forced into the role everyone thought she belonged. Can Giselle find acceptance and love on an alien planet or will she always be nothing more than a warrior's pet?This book has adult content and may have triggers for some.
