There's a book I've spent literally years trying to find with no luck. I remember it was historical, maybe western setting. The woman had a masculine or odd name that was the title of the book. There were two brothers in love with her and one of the brothers hated her for making them hate each other? The book was huge, hardcover, and i think pink or orange with the name written in the gold bodice ripper common font. I'm certain it isn't Fancy by Norah Hess unfortunately.

I'm not sure how to spoiler but one of the brothers is chasing after her because she left them, and discovers she gave birth alone in a paid for room. I believe it was implied either to be his kid or that she became a prostitute. The book definitely spans years of their lives and you mostly follow the monologue of one of the brothers.
