Reaver has a certain charm that made it a fun read. Was this the most exciting book in the entire series? No. However, there were numerous moments where I laughed out loud... in a good way. Reaver wasn't afraid to poke a little fun at itself. There were turns in the story that were so iconic in their cliche-ness that it was just funny. I don't mean that as a bad thing. All those laughable cliches (view spoiler)[ I mean come on! A long lost evil twin brother! Ha! (hide spoiler)] were kind of self-depreciating and just gave the story a bit of a light heart. 
 Did I enjoy Reaver and Harvester as characters? Why yes I did. Thanks for asking! I really liked them as both individuals and together as a couple which is a key factor in how successful I find a romance to be. I really enjoyed all the witty / snarky banter and they were a couple I consistently rooted for. Personally, I think the sexual tension could have been played up a little more. They really didn't have a lot of options or time for sexy times considering they were battling their way out of Sheoul (Hell) for about 50% of the book but still... it could have stood to have had some more heat in it. As for actual smut: It was decent. It wasn't the best I've read and it wasn't the worst. I think there could have been more. 
 I just have one other side note but since its spoiler-y I'll hide it from delicate sensibilities... (view spoiler)[ So, what is the deal with the Archangels? They're like a parade of asshats! Like dude... why isn't anyone overseeing their actions? Especially Raphael! Since when is ordering torture on another angel, blackmail, bribery, stealing an unborn baby, and sexual coercion ok? Why aren't there any ramifications for his actions? The guy gets pretty rape-y (sexual coercion) at one point. Luckily it doesn't happen but if Reaver didn't save Harvester he would have totally gotten rape-y and would have been consequence free. It just feels like a big plot hole to me. All the other species or castes within a species have to answer to a council of some kind... except the archangels apparently! (hide spoiler)]
