All of Her — Carolyn Faulkner

Nate is a defender of the country, a loner who brought himself up from struggling in the streets to excelling in the military, and pretty much everywhere else he set his mind to. Macy comes from solid Middle America, and for the first time he's tempted by strange thoughts of family and home - and she by the unusual appeal of his firm ideas about the home and family that'd be best for her. And a firm hand that doesn't hesitate when a trip over his knee would keep her safe and happy while they build that life.
