Jacey Lawless is a different kind of a lady—fast with a gun, a natural on a horse, and wild of spirit. Her father had once been a desperado; her mother a Boston heiress. Now driven by grief after their parents' deaths, she and her sisters take a blood oath to find the killers. Jacey rides to Tucson to find out more about her father's old gang—and which one of them stole a precious family keepsake, and left a spur behind at the murder scene. What she finds is notorious gunslinger Zant Chapelo, and their two worlds collide.
