Then Jason Chiago comes to town, one of many volunteers here to help rebuild her family's summer camp. Tall, dark, and hot as hell, he's a member of the legendary Shadow Wolves, an all-Native unit of expert trackers who patrol the US-Mexico border. Sadly, he's also taken-or so her friends say.

But he made a deathbed promise to his grandmother that he would never abandon his O'odham people. Winona deserves better than a fling with a man who can't stick around. That's why he's going to keep his hands to himself, no matter how much she makes him burn.When a wealthy rancher asks Winona to help find a wolf that is killing his livestock, Jason and Winona join forces to track the animal.
