Perfect conclusion. Perfect execution. No filler scenes, no extra pages, no lack of pages either. 
 When Damen and Laurent interact, is like reading about a volcano and a hurricane fighting... The tension is almost unbearable; my heart wouldn't stop beating throughout the whole book. And I don't mean only romantic tension, you feel a storm coming, but you don't know when. Anything I tell you would be spoilers, so let's just leave it here. 
 For those worried about the sex scenes and abuse: (view spoiler)[it is OK. The book has none, only a couple of interactions between the main characters, which are sweet and tender. I don't know if the author diminished the tone of the books on purpose, accompanying the character development and the story, or if it was just natural for the story to evolve. Whatever the case, it is astonishing how the tone of the books changed from one to the other (hide spoiler)] 
 Regarding the ending, (view spoiler)[ I think they'll find a lot of resistance and I'm kind of sad because I want them to be happy. Let's just imagine them together and without problems or political struggle. (hide spoiler)]
