Reckless Love by Elizabeth Lowell
A passion as wild and free as the wilderness frontier... No one who roamed the steep green mountains and red-rock canyons of Utah Territory was safe from El Cascabel and his renegade warriors -- not Janna Wayland, not the wild stallion Lucifer -- not even Ty MacKenzie, the stranger who had come for the stallion, and stayed to capture Janna's heart. Now all three must join forces and make their escape, or die trying.
