The Duke Effect by Sophie Jordan

A female in a time when women aren't allowed to be doctors, Nora has taken on her deceased father's name in responding to correspondence about medical matters. But one specific set of letters comes back to bite her.
Formerly of the King's army, Colonel Constantine Sinclair's three male cousins have all died and he is now the direct heir to a duke so he's back in England to learn his new position. He is not happy to learn that the man whose letters he so looked forward to are from a twenty-year-old girl. But then she decides that she is going to insert herself into solving a family medical mystery and proving to Constantine that she really can do the things she promised.
I really struggled with the rating on this one because Jordan is an amazing writer but... I really disliked Nora. She was SO annoyingly headstrong, not listening to anyone else in the story. That can sometimes be overcome if a character's decisions make some sort of sense but Nora's aren't very logical to the context of the story.
