Colton's Montana Hideaway by Justine Davis

She went undercover to escape a killer...and attracted another.

A serial killer’s threats drive FBI tech expert Ashlynn Colton undercover at a dude ranch. Investigating her prime suspect’s half brother, cowboy Kyle Slater, the city girl is unprepared for how displaced she feels on a ranch...or her attraction to Kyle. When Kyle’s murderous father threatens Ashlynn, she and Kyle take refuge at a remote cabin. Now Ashlynn’s greatest danger comes from her own heart.
