Hi sorry this isn't an update but PLEASE keep reading. I'm really sorry I haven't updated but I've been doing a lot of research and please anyone I need to find a book.
The trope would be a princess, a prince and a dragon but the dragon would be a shape-shifter, so the dragon could shape-shift from a person to a dragon. And it kidnaps the princess. It honestly doesn't matter why but there about the same age he's maybe a few years older. He keeps her in a tower, you know basic princess story but over the course of the book they are getting closer and he's starting to fall for her and eventually he's falling in love with her. The day he's going to tell her that he's in love with her they get in a huge fight before he can tell her. He storms off and doesn't come back till the next day and when he goes into her room to apologize and tell her he loves her, she's not there so he goes through the tower looking for her. Till he goes to the front of the tower to see her on the back of a horse with a prince on the horse with her. And she'd look back to see him standing. Then it would just end like that.
I really want to find something like this, please help!
