The body of a young gay man buried along the Rio Grande leads Albuquerque police detective Chris Gutiérrez down a path of dark secrets and old hatreds. Trying to deal with the other detective assigned to the case-the sexist and homophobic Dale Harper-Chris tracks the killer to an older unsolved case, and to the doors of a local megachurch and a popular minister with ties to ex-gay groups. Enlisting the research skills and networks of sociologist and best friend K.C. Fontero, Chris works to build the case and make an arrest before the killer strikes again, even as she must also face her growing feelings for attorney Dayna Carson. Struggling with her attraction to Dayna and the complexity of a difficult case, Chris is drawn into an ominous and potentially deadly game of cat-and-mouse with a man who might kill to protect his own secrets.

When a man is shot to death in his house near Albuquerque's Old Town, homicide detective Chris Gutiérrez is called to the scene with fellow detective Dale Harper to investigate. They soon discover that the murder victim may have been involved in human trafficking over the Mexican border, and that he may have attracted enemies in an underground network with its own code of honor. Did someone in that network kill him? Or did his past finally catch up with him? As Chris works to find answers, she also draws the attention of a local anti-immigrant blogger who will go to any length to post damaging and personal information about Albuquerque law enforcement officers, and she knows that her partner, prosecutor Dayna Carson, will be part of that campaign if the blogger discovers their relationship. She has to find a way to watch her back and keep Dayna and her friends and family safe from the blogger's large audience and prying eyes, even as he dogs her every move. From Albuquerque to El Paso, Chris is on the trail of a killer who seems to be able to disappear into the cultures on either side of the border, like a ghost or desert wind. Those along the border protect their own, Chris knows, but she has a job to do, even as she draws closer and realizes that sometimes, things aren't what they seem.
