Coral Rustling by Charlie Richards

On the Road: When a coral snake shifter succumbs to boredom, he learns the value of interaction.

Ulkna has spent the last three decades existing in his coral snake form. For most of that time, it was forced on him by witches. After being rescued over a year before, it was just easier. Then Ulkna overhears the shifters he’s staying with talking about something that he’s always enjoyed—horseback riding. So, he shifts.
While the guys are surprised, they welcome Ulkna on their Grand Canyon adventure. There, he scents something shocking…one of the horses that makes up the string of riding mounts is his mate. Finding him is easy, as Trey recognizes him, too. Getting Trey to leave his job as a trail mount is something else.

Can Ulkna overcome his loner tendencies enough to understand the importance of family and its implications on his relationship with Trey?
