Sacrifice on the Border by Cecilia Domeyko

When Yoali's child is torn from her arms as she crosses the river that divides México and the U.S., she begins a desperate search for him on both sides of the border. As she and Frank, the policeman who loves her pursue the trafficker who has kidnapped the boy we realize that the challenges they face aren't so different from those real life migrants face as they make the crossing in search of a better life. This is a gripping love and adventure story interwoven with dark themes of violence, corruption, and drug trafficking, but most of all child trafficking.
