I adored this book. Stephen is the best sort of romance rake: he genuinely likes women, he never hurts anybody, and he never pressures Rose to risk anything she doesn't want to. He loves her for her brilliance and the way she sees the world, and he makes it clear that if she marries him he'll support her continuing her work. Rose starts the book having learned to keep her head down and stay out of trouble as a method of survival; by the end she learns to take a stand for herself and her family, and when to dare to be a little bit outrageous. And when she *does* stand up for her sister... I can't give specifics without spoilers, but I love that Stephen joins in by threatening to help her rather than taking over the lead. Courtney Milan just writes the best beta heroes.
This *might* have became my new favorite Courtney Milan novel, except that as a novella, there just isn't enough of it to unseat the wonder that is The Suffragette Scandal. Which isn't to say that it feels too short in itself: it is exactly the right length for its own purposes.
