I'm so glad this series was great all the way through. I did expect some kind of let down with this story but it went pretty smoothly with some great plot twists and some even better surprises. 
 This series is definitely epic when it comes to a fantasy. My greatest love of the series is while it is a fantasy story it takes place mostly in our world. Moning develops a wonderful heroine in MacKayla Lane and as we move through the story we get to see many of Mac's doubts while we, as the reader, continue to believe that Mac is important and will do the right thing to save the world. 
 The greatest variables in the story are Darroc, V'Lane and Barrons. Darroc is an ex-Fae and was in the book The Immortal Highlander. He's angry that he was turned into a human and we learn in the previous books that he was dating Alina (Mac's sister who was murdered). Mac continues to believe that Darroc was her murderer but Darroc insists that he loved Alina and while she knew about him and was upset by it; he believed she's come back to him. Got to read to find out the truth. 
 As for V'Lane. Seelie Prince who has been trying to find the book for his Queen. He takes a liking to Mac and continues to spend time around her. In Dreamfever V'Lane starts taking Mac to tropical beaches for the day (a major Mac weakness). We gradually see his idea of humans change... or do we? What mysteries could this Fae Prince be hiding? Read it. 
 Barrons. Man o man. If you've read any of this series you probably adore him as much as I. He's ornery, stubborn and doesn't tell Mac a thing. But could there be a reason why he doesn't tell her things she feels he should? And in the end of the fourth book was it Jericho Barrons Mac killed? We find out a lot about Barrons and the men who entered the Abbey in the beginning of book four to rescue Mac from being Pri-ya, but you'll have to read the book. 
 Not only are we getting to see the characters Moning developed in this series but some from her previous series (below). We get to see the MacKeltar's and Adam in this book and I enjoyed every minute with them. Christian is a newer MacKeltar to the stories but just as interesting. I'm truly hoping he gets his own story. 
 Moning does a fantastic job wrapping up there series while simultaneously opening up other avenues for another series or more stories. The best part is everyone you're left wondering about at the end would make a great future story.
