Viola Caroll fought as a soldier in Waterloo; when she was left for dead on a battlefield, but nursed back to health by farmers, she decided to renounce her old life as a viscount and live as her true self, a woman. At the start of the story, only her younger bother and sister-in-law know the story of Viola's past. But a cry for help brings her back in contact with the Duke of Gracewood, her childhood best friend, bosom companion, and fellow Waterloo survivor. Viola had decided the best thing she could do was cut off her old friend and never reveal to him that she lived. But she finds him haunted by fears, addictions, and PTSD; left with a permanent limp and a terrible grief, he is barely surviving. She commits to caring for him temporarily, but when he begins to fall in love with her, Viola feels trapped between her own feelings and her fear of telling him the truth of their past. This historical romance is almost completely free of homophobia and transphobia; what ends up separating the characters for much of the story is not their genders or sexualities but their social class. The cast of the book is rounded out with a delightful set of quirky family members, from Gracewood's dreamy oddball of a teen sister to Viola's  Mrs Bennett-like sister-in-law. 

I read so little romance, I don't even have a virtual shelf for it. I liked this one, but also thought it was at least 50 pages too long, and wished the pace had moved more quickly through some sections. The tone switched from humor to melancholy very abruptly sometimes mid-scene, and the final confrontation with the main villain was a bit ridiculous, but ultimately I did enjoy the book.
