Standing between him and exoneration are a corrupt mayor, a crooked sheriff, a notorious cathouse madam, a sly bootlegger, feuding moonshiners . . . and a young widow whose soft features conceal an iron will.

Her success quickly makes her a target for cutthroat competitors, whose only code of law is reprisal. As violence erupts, Laurel and—now deputy—Thatcher find themselves on opposite sides of a moonshine war, where blood flows as freely as whiskey.
