The Heroes where abusive to the heroine in her childhood and the reason was completely pathetic. I mean honestly scar from being conjoined twins, really, and because she was a photography nut and she "may" take a photo of two boys who never uncover their scar and guess they were conjoined twins, really!!!
The heroes continue this pattern of abuse now they are all adults, she returns to her home town for her job and attends a reunion. The heroes running around all possessive restraining each other from beating up other men who talk to her. Meanwhile she is have a none to convincing difficult time of dealing with the expectations of staying at home. Manipulating her hiring of a guide in to Yellowstone, and threatening to follow her despite her considerable experience and she just gives in, so she is "forced" to take them. They have lots of sex in the wilds and return when a family member conveniently dies and leaves her his ranch, she runs away. After a short time rather than getting the message her cowboys follow her, threaten her friend and all's well.
