Honor Bound (The Montana Hamiltons, #6)

Protecting her life will mean betraying her trust 

Ainsley Hamilton has always been the responsible one of the family. As the oldest daughter of presidential candidate Buckmaster Hamilton, she's also a potential target. For months she's sensed someone following her. When an expedition to scout locations for a commercial takes a terrifying turn, she's rescued by a natural-born cowboy who tempts the good girl to finally let loose. 

Sawyer Nash knows just how reckless it is to fall for someone he's gone undercover to protect. Yet masquerading as an extra on set, he starts to see beneath Ainsley's controlled facade. And with the election—and a killer—drawing closer, Sawyer stands to lose not just his job and his life but the woman for whom he'd gladly risk both.
