To appease the demons that are coming into the world through a newly-opened portal, and get on their good side, the Emperor decides to give them one of his high-ranking slaves as a gift. Now, she must use all of her wits not only to survive among them but also to learn as much about them as possible if her people are to have any chance of survival. However, she quickly realizes that these demons are nothing like she expected them to be. Chronologically speaking, this book is a sequel to Twisted hell. But it has a new cast of characters so you don't need some knowledge from the previous book to follow this one.
