Book excerpt: Driving across the Arizona desert, Sally Jasper collides with a man who sprints suddenly out of the sand. The man - an illegal Mexican immigrant - is killed upon impact. Haunted by a rising ghost of guilt, Sally vows to set things right again. She soon learns that the dead man was being chased, and the gang of vigilantes who were pursuing him is as dangerous as they are unpredictable. Sally realizes she has something in common with the dead stranger: a yearning for freedom. This desire leads her to form an unlikely rock-n'-roll band called Radio. Sally uses the band's performances as a front to conceal her perilous plan to smuggle a Mexican family across the border. But her task is complicated by her budding romance with an Immigration officer. Her days become a minefield, where one misstep will cost her everything she holds dear. Fugitive Shoes is a story of three women's efforts to let go of the past, to find unexpected love, to mingle with dangerous people, and to thwart the law when the law seems wrong. Most of all, it is a story of libertad. Freedom.Erin O'Rourke lives in the American southwest, and is the author of the best-selling novel, Seeing Pink.
