Under Cover of Darkness — Elizabeth White

MURDER UNDER THE BRIDGE

On a hot Texas night, border patrol agent Jack Torres watched in horror as his partner was fatally shot. His faith shattered, Jack vowed to take down his friend's killers. His quest for vengeance brought him to lovely landscaper Meg St. John, who hated the border patrol because they hassled her workers, and was too innocent to see the dark truth: men were being sold as cheap labor.

Working for Meg undercover brought unexpected feelings -- and grave danger. Because someone was working against him. Jack had to protect his lady boss and get the job done without getting them killed...or blowing his cover.
