Max wakes up in a realm not his own, but Darke is there to protect him in any way he can, even if it means taking the human to bed all night long.
A marine unit is on assignment to clear terrorists from caves in Afghanistan. An explosion later, Max Whitfield is being sold as a slave in the daemon realm of Thorash. He doesn't know where he is, but one thing he does know, he is no one's slave. When a fight breaks out, three men from Max's unit escape, but he is stung by toxic venom that will kill him as it brings excruciating pain.
Darke, a Carthus daemon, is part of Thorash law enforcement. His current assignment is to stop the illegal import of humans to be sold as slaves. Instead of meeting his contact, he rescues Max from certain death and takes him back to his home. The only thing that will save the human is hot sex all night long.
When two warriors, who have nothing in common, find themselves thrown together, they will do what they must to complete the assignment. Even if it means giving each other up forever.
