Tina Cahill, newly arrived from the East, is determined to get the saloon in Broken Wheel, Texas, closed for good. To that end, she pickets outside the place every afternoon. Unfortunately, so far no one has paid any attention.
Vince Yates earned the nickname "Invincible Vince" because of his reputation for letting absolutely nothing stop him. Not his tyrant of a father. Nor the injuries he suffered in the Civil War. Nor the fact that he is Broken Wheel's only attorney and sheriff yet has no law degree.
But Vince is about to face his biggest challenge yet: his past has just caught up with him. His father, mother, and the sister he didn't know he had show up in Broken Wheel without warning. His father is still a schemer. His mother is suffering signs of dementia. And his surprise sister immediately falls for one of Vince's best friends. Vince has a lot of people to take care of, and Tina doesn't approve of how he's handling any of them. But with almost all the other men in town married off, Vince finds himself stuck with feisty Tina over and over again. Of course, Tina is the prettiest woman he's ever seen, so if he could just get her to give up her causes, he might go ahead and propose. But he's got one more surprise coming his way: Tina's picketing at the saloon has revealed a dark secret that could put everyone Vince loves in danger.
