For as much as I loathed the MMC for the first 75% of this book, it really did have a phenomenal ending. This is starchy Duke levelled by illegitimate society scandal, and by the time this man was well and truly humbled, I was (finally) rooting for him. We had an on-the-knees grovel, and a sense that our two main characters had finally achieved equal footing in their relationship (which is Fraught with stressy power imbalance for a majority of the book). Readers might not love the betrothal storyline for the Duke, because it he is technically betrothed (to a character who is not the heroine) for a portion of the book (when he is absolutely intimate with the heroine), but it is very clearly established as a business match by both parties. That said, for readers with a hard line on infidelity, this may be a deal-breaker!
