When Shelby Holt convinces a friend to work at Wildhorse Pass tourist ranch, she never imagines he will die there. The police say Michael's death was accidental, but Shelby doesn't believe it. Haunted by guilt, she puts her academic career on hold to investigate. Just back from the Middle East, Chad Graham is guilt-ridden over Michael's death too. He poses as a ranch hand at Wildhorse Pass to investigate the woman claiming his cousin's death is suspicious. Were the police wrong? Or is Shelby hiding something? Shelby knows she can't trust her heart, but when it comes to Chad, she can't trust her head either. He looks uncannily like Michael. Yet even as their distrust deepens, sensual attraction simmers between them. The closer Shelby and Chad get to answers—and to each other—the closer they get to danger...and to a killer who will stop at nothing to avoid discovery.
