U.S. Marshal Kelsey O'Brien has been waiting all her life to work with someone who can understand her ability to "see" the past. Now she has her chance.
Together, Kelsey and Logan follow their instincts to the Alamo and to the newly reopened Longhorn, which once tempted heroes with drink, cards and women. If the spirits of those long-dead Texans are really appearing to the victims before their deaths, only Kelsey and Logan have the skills to find out why....
