"Duke of Desire" is extremely well done; I adored Iris and Raphael and I desperately wanted them to find their happy together. Raphael is that super-damaged sort of broody, but Iris has more than enough steel in her spine to face him down and make him like it.
I loved the back and forth between Iris and Raphael, where she chips away at his self-loathing and belief that he doesn't deserve happiness. If there's anything that I thought lacking - it was that the epilogue wasn't longer.
That said, a word of warning - "Duke of Desire" deals with some very dark material. Pedophilia, rape, and forced incest are referenced at multiple points. Those who are uncomfortable with such things should be careful when reading.
I'll be honest, "Duke of Desire" is really well done, but I can't give it five stars because I truly can't say that I "enjoyed" it. But that's me. None of the aforementioned is explicitly spelled out, but it is a major underlying thread of the book.
Sometimes when an author has written more than ten books in a series, I find that it starts to get repetitive or that characters / plots get re-used. I haven't noticed this to be the case with the Maiden Lane series. "Duke of Desire" stands alone very well, but there is enough of previous characters that I'm interested in reading about them as well.
A LADY OF LIGHT Refined, kind, and intelligent, Lady Iris Jordan finds herself the unlikely target of a diabolical kidnapping. Her captors are the notoriously evil Lords of Chaos. When one of the masked-and nude!-Lords spirits her away to his carriage, she shoots him . . . only to find she may have been a trifle hasty. A DUKE IN DEEPEST DARKNESS Cynical, scarred, and brooding, Raphael de Chartres, the Duke of Dyemore, has made it his personal mission to infiltrate the Lords of Chaos and destroy them. Rescuing Lady Jordan was never in his plans. But now with the Lords out to kill them both, he has but one choice: marry the lady in order to keep her safe. CAUGHT IN A WEB OF DANGER . . . AND DESIRE Much to Raphael's irritation, Iris insists on being the sort of duchess who involves herself in his life-and bed. Soon he's drawn both to her quick wit and her fiery passion. But when Iris discovers that Raphael's past may be even more dangerous than the present, she falters. Is their love strong enough to withstand not only the Lords of Chaos but also Raphael's own demons?
