This HaBO is from ppyajunebug, who is looking for a book from a while ago:
Okay, so it's not 100% a romance, but it definitely has ~strong romantic elements~.
This was a YA book published in the early 2000s, I believe. It took place during the Civil War- the heroine lived in northern Virginia and her older brother joins the Confederacy.
At some point she meets a Union soldier, at another point she somehow gets suspected of being a Confederate spy and thrown in jail, and then the Union soldier proposes to her and they get married.
I'm pretty sure the cover had a girl in a blue dress looking out a window. I remember loving this book, partly because it all happened in my hometown and partly because there was ~kissing~.
Help me, please?
Oh, this sounds like terrific YA historical. Do you recognize this book?
