Wildfire
U.S. Marshal Parker Denison is annoyed by the unsolicited help of Tyler O'Neal in his pursuit of the outlaw who killed her brother, until he finds himself at her mercy.

Nobody can stop fiery Tyler O'Neal from going after the vicious killer who murdered her twin brother. Certainly not a handsome loner like U.S. Marshal Parker Denison, who has no tolerance for a headstrong young woman tagging along while he races to apprehend the outlaw. But when Parker ends up in an abandoned cabin with a bullet in his shoulder, he is at the mercy of the beautiful Tyler, who tends to his wounds, and innocently torments him with her every touch. He cannot let her ride off alone on a crazy killing mission, yet restraining this angry hellion with the force of his own body is the spark that turns smoldering passions into a raging wildfire of love.
