Wind River Undercover by Lindsay McKenna

Hide in plain sight.
For native Guatemalan Anna Navaro, nothing is more satisfying than capturing drug traffickers for the U.S. DEA. Her career has always been her focus, but just as she’s beginning to yearn for something more, she’s given a brand-new assignment with DEA agent Gabe Whitcomb. In his well-worn Stetson and boots, he’s part cowboy and part law enforcement, a combination Anna finds irresistibly sexy. But desire has no place on a job as dangerous as this one, because the drug lord they’re after is the violent fugitive who killed her father . . .

Gabe’s worked some treacherous assignments in the past, but this one raises every alarm—and not just because his partner is a gorgeous woman with the grace of a cat and a sniper’s deadly aim. He and Anna are being sent to the Wind River Valley where he grew up—and where his adoptive parents still own a ranch just eighty miles from the Elson family, who have been recruited into the ruthless Gonzalez cartel. Posing as new ranch-owners and ingratiating themselves with the Elsons to uncover evidence, Anna and Gabe can only fight the heat flaring between them until they realize that building a life together, here in Wind River, is worth risking everything for . . .
