Rugged Zach MacKenzie has a dangerous secret that could cost him his one chance to win the woman he wants . . . Rose Dubois became a Harvey Girl and came West looking for a new life and a husband—preferably a wealthy rancher. She certainly knows better than to get involved with a no-account cowboy like Zach MacKenzie. He's strong and good-looking enough to stop a girl's breath—but the dangerous ruffians he runs with are surely heading for bad ends. So why can't Rose calm her pounding heart whenever he's nearby? But Zach's only pretending to be no good in order to infiltrate an outlaw gang. If he tells Rose he's really a Texas Ranger, not only is his mission in jeopardy, but both of their lives as well! Yet this spirited filly is everything he ever dreamed of. Her lips are downright irresistible, and her passionate fire burns hot enough to make a smart man do something real stupid . . . like fall in love.
