Sojourner: A Time of Intolerance — Daniel Copeland

All Karen Parker wants is a fresh start. Simple as that. She doesn't want a fight. She doesn't want to battle with a drug dealer. She doesn't want to be a national security threat. As far as she knows, her children want the same things. Then her son, Tommy, disappears with a mysterious man. Tommy's disappearance thrusts Karen into a desperate search pitting her against nature, time, and killers. Her only ally is an enemy from her past named Sam Henry. Karen is not the only person who wants to find Tommy, but she is the only one who wants to find him alive.
