Teaching Miss Maisie Jane by Mariella Starr

Jake Maddox is an Arizona territory lawman whose moral compass has been bent too many times. He is ready to retire from the law, become a homesteader and find a wife. He has got his mind set on how a wife should and should not behave. He has a quick temper, doesn't like sass, and his words will be heeded, or someone is going pay with a spanked bottom.

Maisie Jane Jackson is an eastern genteel belle, too young, too spoiled and too stubborn to know what is good for her. In a fit of temper, she winds up on the wrong side of a whorehouse-owning hanging judge and she needs a rescuer. When these two collide there is not much doubt about who will win the battle of wills.
