New Mexico Nymph (Trailsman Series #268) by Jon Sharpe
Skye Fargo’s under the spell of a sinful señorita!
When Diego Madrid’s sister-in-law Marga decides to run off and get herself into another big heap of trouble, he decides to put his ample means to use—and hire the Trailsman to bring her back.
But Marga’s no damsel in distress. With her beguiling beauty, even Fargo begins to fall under her spell. And with gunmen following close behind, he’ll have to break the curse—or follow the devil’s eyes straight to hell.
