I don't want to tiptoe here trying not to give some things away so this review contains SPOILERS! Huge spoilers! Be aware! 
 I have different standards for rating last book in the series. I am interested in how author ties all lose ends and if the book will reach this final point to which all previous books were leading. And I feel that Dark Swan series ended where it was supposed to. 
 I was so afraid to start reading it. I was afraid to be disappointed by the choices Eugenie would make (and we all know that she did a lot of stupid ones before). But for once she did good. 
 But let's start from the beginning. The book starts with Eugenie being pregnant and her enemies are hunting for her. So she made difficult decisions and run to the human world to some small town where nobody will be able to find her. There she gave birth to twins. 
 I found this part of the book a little bit boring. Nothing really was happening except for Eugenie worrying about her safety or Eugenie whine about how bored she was. Not enough dialogs ether. 
 But what I really don't understand is why Richelle Mead felt the need to bring new character (Evan) into the book. He didn't have any role in any of it and only made me nervous, because I was afraid that Ms.Mead would decide to leave Eugenie with him (she is unpredictable like that). But since she didn't I am again wondering what was he needed for? And Eugenie once again played everything wrong. She saw his interest in her and didn't want any of that. So my question is why haven't she done anything about it? There is a lot of ways a woman can discourage a man. Or does she like having poor men in unrequited love with her? Does it boost her ego? 
 Then after the twins are born comes the second part where Eugenie is back in the Otherworld to help break the curse that devastated her lands. I liked this part very much. The adventure was full of events, actions were good and the entire quest didn't feel forced or unnatural like in the Iron Crown. But what is more important in this part is that the big Jerk is back and Eugenie is forced to work with him. And that is where I was really worried, because we all know that when it comes to Kiyo, Eugenie is not the best judge. But again, she surprised me and for the first time saw him for what he really is (which is an asshole!). 
 And then the final part, which resembled Indian movie and soap opera merge in one. This part is about the Storm King's heir. I saw it coming. The hints in the begging were too big not to make connections. All this talk about how alike they all are and how powerful the boy is made me understand what was going on. But this problem is solved too by some bitch queen. 
 And then the most ridiculous thing in the entire book happens: Eugenie talk with Kiyo. Vasectomy???!!! Seriously? And all this talk about conception time is far stretch. Yes, it is possible, but it is not very believable, that a gentry who has problems with fertility would conceive a child on the least probable time for it. But even before this talk I wondered about twins' father. Haven't Eugenie had biology classes is school? Kiyo is half-Japanese, his genes are dominant! And yes if he is heterozygous than Eugenie's children can have blue eyes, but that is small probability. And when there is nothing at all from the father, you should stop and think why. And I understand that Ms.Mead needed to give us a happy ending but Dorian would love these children even if he wasn't their biological father. It would only endear him to us. I am glad for them. I just think that there should have been more finesse explanation. 
 Conclusion: I am very relieved to know that she picked Dorian. I still think that Kiyo should have died or at least be punished in some way. And I am upset about Eugenie's decision about her children. I understand why she did it, but it is not how it was supposed to be! They were supposed to be one happy family. But I suppose she wouldn't be Eugenie if she didn't make at least one foolish decision in the book. I just can't see her and Dorian happy together with this huge secret between them. And he has the right to know. I will just imagine that she told him and they are happy. 
 I love this series and it had a satisfying ending. I will miss them all. 
 P.S. Dorian, I love you. If you ever decide to dump Eugenie, you know where to find me...
