Gracie Billings is at odds with her life on Carson Hill Ranch. Having shown up with her sister six years ago as a scrawny, needy child, she has grown into a beautiful girl and a capable horsewoman. But everywhere she turns, she's thwarted in her attempts to contribute like a real cowboy. Seamus Carson has practically grown up with Gracie and has always seen her as the kid sister that fate denied him. When he begins to realize that there's something special about Gracie, his fears of his family's reaction to the news keep him from seeing her as anything more than the sister he's always picked on. Will Seamus and Gracie admit their feelings for each other, or will they continue to deny themselves until the day it almost tears the family apart?
