Texas Ranger Rory Yates is not keen for hero status. But it's unavoidable once his girlfriend, country singer Willow Dawes, writes a song about his bravery. Rory escapes his newfound fame when he's sent to the remote West Texas town of Rio Lobo, a municipality with two stoplights. And now, according to the Chief of Police, it has one too many Texas Rangers.

Rio Lobo Detective Ariana Delgado is the one who requested Rory, and the only person who believes a local councilwoman's seemingly accidental death is a murder. Then Rory begins to uncover a tangle of small-town secrets, favors, and lies as crooked as Texas law is straight.

To get to the truth before more people die, Rory is forced to take liberties with the investigation. The next ballad of Rory Yates may not be about a hero, but rather an outlaw song.
