I'm giving the entire series a 5⭐ rating over all.   

For a reverse harem this series ranks with the best of the genre.  The MMC is fantastic and truly kick ass.   I admit I had this marked as a DNF to start with as I thought the book was heading in a different direction with a MMC that would spend her time running from her fate for books just to create a fake sense of yearning and slow burn.  But instead there is enough of a story to leave that sentiment in the dust 

And this was a great 4 books of story that doesn't waste any time before the next plot point.  

The four MMCs are given enough time to develop and while they fit the typical RH archetypes I can't complain when that is the reason I read these books. 

Sometimes the last book of a series can be a disappointment or too rushed but I felt this book did not falter in its pacing or content.   

If there is anything I would complain about is that I love my HEA epilogues with babies and toddlers.  But apparently this is a hated and unpopular trope and is usually avoided so I can't fault a writer for not including it.  I will have to just pretend that there are cute little dragons and fae casters and incubus and elementals running around.
