When Hannah, a seventy-three-year-old widow, finds the semiconscious body of a fourteen-year-old Mexican national in a ditch along a remote central Texas road, she has no idea someone is watching. Not until the girl's brutal attacker arrives at Hannah's door in the middle of the night, threatening not just the girl's but Hannah's very survival. Ultimately the question of justice for a victim of human trafficking and the woman who helps her lies in the hands of a biracial border patrol officer and an unconventional small-town sheriff.

The I-10 corridor of Texas connects saints, demons, and victims as the ultimate question of life and death is decided by two strangers fate has bound together. They must make a hard choice in order to survive: either follow the law or follow their consciences.
