Knox by Jae Greyn

We don’t get time. We get traded to the highest bidder to keep the world turning. We can break down in private but we can’t change our fate.

In a world where ancient clan law mixes with modern-day society, Josh is stepping into the spotlight as a Graeme. All he wants is to leave behind the boy he was and find his place as a normal person.
Things are finally falling into place. He has a great boyfriend, a good job, and his family accepts him. But his world is shattered when, in a brutal Tri-County tradition, his boyfriend is traded into an arranged marriage for a horse, destroying Josh’s newfound sense of safe.
The man who trained that horse is Knox Daniels. Third born and three minutes too late to be the heir, his father uses his horse to seal the deal and expects Knox to fall in line and join the Navy.
But Knox has other plans. For fifteen years, he has secretly loved the pretty blue-eyed boy who just ended up with his horse, and he is determined to claim the boy who has always been his destiny—no matter what fate the Macs have planned.
