Corin and the Courtier by Eliot Grayson

Most people run from beasts, not to them…

Aster didn’t put much thought into his escape. All he knew when he ran up that mountain—straight into the lair of a grumpy dragon knight with a huge grudge against his family—was that he couldn’t submit to an arranged marriage. It never occurred to him that a snowstorm would strand him there. Or that he’d give in to years of longing and beg for the monster’s forbidden touch. But it happened. All of it…
Corin wasn’t trying to be a hero—especially not Aster’s hero. He couldn’t very well let him die, though. So he protected him. Which might have been considered noble…if he hadn’t also fallen into bed with him. Over and over again. But the cost of keeping Aster is far more than Corin’s willing to pay. Corin will eventually be forced to let him go—even if it destroys him.
When Aster’s problems follow him up the mountain—literally—he realizes running is no longer an option. The only question now is whether Corin will fight for him, or burn their potential happily ever after to the ground…
