The Texan — Joan Johnston

Owen Blackthorne was a lone wolf, a man who didn't need anyone. Until Bayleigh Creed appeared on his doorstep, demanding his help in locating her missing brother. They headed into the desolate West Texas wilderness together, a Blackthorne and a Creed, mortal enemies obliged to join forces to survive. Neither counted on the unwanted attraction that drew them together, or the bitter truths that would force them apart. Until the ruthless wilderness compelled them to make life- and- death choices--between family . . . and duty . . . and love.
