In the final volume, the heroes Saker, Ardhi, and Sorrel return to Ardrone from the Spicerie for their final confrontation with Fox. Upon arriving they realize that the oak shrines have vanished and that Fritillary is dead with Fox having succeeded her. The king of Ardrone is no longer the master of his senses and lets the Grey Lancers lay siege to his son's castle in order to get his grandson who he has proclaimed his heir. Amidst all the chaos and destruction our trio has their work cut out for them.
One of the things I liked about this series was that it had a truly evil villain. He comes from a family that has been killing babies for centuries for power. But he still manages to surpass them when it comes to committing horrible acts, as he not only rapes women to father illegitimate sons, which he then raises so that they can use their powers in his stead, he also kills them to sustain his own power. This guy is quite simply beyond contempt.
I also liked how the series portrayed prejudices such as the Va-cherished and the Va-forsaken hemisphere, but also the royal children, Mathilda and Rhys. Mathilda is a spoilt brat, but you understand where she comes from. Mostly because of her interaction with Sorrel, who in a way had suffered the same fate, but also through Saker's compassion for her, which was why he was understanding of her betrayal. And in the third book, Rhys finally became a true ruler. There is a scene about the needs of the many outweighing the few. Saker is angry at Rhys, but then Juster explains to him, why this has to be done. It reminded me of a movie I saw a long time ago called The Musketeer. If you don't know it, don't bother, it was horrible. In this movie, the villain wants the queen to sign a letter that will entice a war. To force her hand he threatens the life of a servant, who happens to be a child. Thus the queen signs and I thought to myself that's a horrible queen. She just sentenced thousands to death to save the life of a single person.
Having said that, I got the impression that either the author hadn't planned her series until the end or changed her mind at some point because there were certain aspects that didn't make an awful lot of sense.
For example, Saker's origin, which featured quite prominently in the first book. Even Fox remarked about it and Saker went to confront Fritillary about it. In this book, the secret is revealed. I had actually guessed who his father was. But it has no impact on the storyline or on Saker as a character. And it makes you wonder why Fritillary was still cagey in the first book when Saker was more than old and mature enough to get it.
Another example would be Fox's ascension to Prime. Fox must have planned all of this for quite some time. While the Grey Lancers were something that wasn't implemented until recently, he needed his children to reach a certain age. Some of them are in their twenties. But then it is mentioned in the book that Fox being appointed to Prime was basically a coincidence because the king started hating the shrines for not being able to save his wife.
The last example is the relationship between the three main characters, which actually is true for the entire series. In the first book, Sorrel fell in love with Saker. Though that relationship wasn't exactly deep as it was mostly a result of Saker being handsome and the polar opposite of Sorrel's husband. It, however, ran deep enough for her to risk herself to save him. When he inadvertently dragged her and Piper to the Spicerie, she was of course very angry with him. Ardhi barely featured in the first book. In the second book, everyone is angry at Ardhi as he is the true reason why they all have to go to the Spicerie and he did control Saker for a while. By the end of the book, this turned into camaraderie and Sorrel convinces him not to sacrifice himself. And according to the birds, there is a love triangle blooming. On the yearlong voyage from the Spicerie to Ardrone, the relationship between Saker and Sorrel suddenly turned into something akin to the love between siblings, and Sorrel was madly in love with Ardhi, even if Piper always came first. Mostly because Ardhi is handsome and he needs her because he is an outcast. Theoretically, he still could have gone to Pashali, where he has lots of friends and used to study.
Overall I really liked this series. I just found it sad that when it comes to character building the series didn't keep the promise from the first book. The relationship between Sorrel, Mathilda, and Saker was more complex than all the relationships later in the series. The author kind of dropped the ball there. This might be the reason why I found the characters likable, but a little flat. I still intend to read more from this author.
