Sometimes, the only choice is the one impossible to make.

Sabin loathes the desert, which makes living in Hell the opposite of fun. Luckily for him, he can avoid the sand and the heat as long as he stays in the palace, and with as much work as he does for Berith, he doesn't plan to leave anytime soon.

Until Berith orders him to.

Zeno is a loner, and for good reason. He's known as The Mercenary, and he's Hell's bogeyman. People are afraid of him, and he's fine with that because it means they leave him alone.

But when Zeno stumbles onto a convoy attacked by a group of demons, he stupidly decides to step in. He ends up saddled with a pretty palace boy, Sabin, and agrees to take him back to the palace-for a price, of course.

Neither of them expects to fall for the other, but they soon realize it's not impossible. What is impossible is for them to find a way to make things work between them. Sabin belongs in the palace, while Zeno belongs to the desert.

How can they be together?
