For 16 years, Wren Cameron's life revolved around her identity as a high-school chemistry teacher, wife, and mother. But her past comes alive after militia extremist Jeremiah Hunter kidnaps her and her teenage son, Daniel, and takes them to his camp, camouflaged in a rocky, secluded landscape. In the past, Wren excelled at constructing bombs and was also Hunter's lover. As the weeks pass, Daniel falls under Hunter's charismatic personality and takes to wearing a gun. All that Wren can think about is escape. When she does, it's an ordeal in which the terrain, snakes, dehydration, and the spirit of her Cherokee grandmother combine to test--and strengthen--her. Although recaptured, she is even more determined and will go to any lengths, including combat training, bomb testing, and Hunter's bed, to plot her and Daniel's eventual escape. Meanwhile, behind-the-scenes maneuvers of the FBI and descriptions of how her husband and daughter cope with their missing family members add dimension to this suspense novel.
