But if he wants to crack the case, he’ll have to work with Texas Ranger Gisella Hernandez.Brock feels the case is way too dangerous for a female agent-especially one who refuses to admit she needs protection. Yet as they work together under the most dangerous threat of exposure, Brock discovers Gisella is stronger than she seems. And that his cowboy heart isn’t so tough, after all.
