City-Boy by Beau Brown

Omega Sawyer Thornburn is having the worst day of his life. His beloved Granddad just died, and the same day he discovers his alpha, Jeremy, is a sneaky, lying cheat.
Alpha Tex Bronston grew up on The Tumbleweed Dude Ranch owned by Sawyer’s Granddad. He remembers butting heads constantly with Sawyer when the younger omega spent his summers on the ranch.
When Sawyer inherits The Tumbleweed Dude Ranch from his Granddad, he flees his cheating ex and high stress job in Los Angeles to start a new life in Red Sky, Texas.
Unfortunately, no one on the ranch wants him there.
