Books with title Cowboys

Rose lost her family when she was only ten years old. A year later she was adopted and had high hopes of finally being part of a real family again. But the Walkers are abusive and their son Chad is a perv. He's always lying to his parents and getting her into trouble. Now she's about to start her senior year of high school, and thankfully Chad isn't there to bother her anymore. But even in her new school there are people that take an instant dislike towards her, even though she doesnt know why at first. At least she has the Campbell boy's, Xander and Clint. They quickly become protective of Rose and when they learn about what's happening to her at home they give her an ultimatum. Leave the Walkers or they are going to do something about it. But she can't just leave before she turns 18 or the police will just take her right back to the Walkers, who will punish her the moment the authorities arn't looking. What will happen, can Rose escape from the Walkers with the help of Clint and Xander, or will the Walkers punish her to far, ending her life before it can even really start.
