Look at Her and Die by Lani Lynn Vale

Posy “Doc” Hicks has high blood pressure. All thanks to a certain hazel-eyed blonde who drives him absolutely insane in her short shorts and cowboy boots.
At first, Searcy Hodges is just a passing fancy.
A look but don’t touch kind of girl.
She has a bad attitude, an even worse bedside manner, and a chip on her shoulder the size of Texas.
It would be wise to stay away, even if that attitude of hers really does great things for him.
But how is a man supposed to stay away when her temper is just that spectacular to experience?
He’s literally watched Searcy make one of her customers cry and not care.
She’s the poster child for ‘don’t do this if you want to stay in business.’
Yet, everyone keeps coming back.
And she keeps shelling out the attitude.
