*spoilers for The Queen of Attolia*
Like the previous book, this has a third person narrative. It mainly follows Costis, although towards the end we get the POVs of other characters. I did somewhat miss following Eugenides around, I knew he was plotting and conspiring but Costis didn't. I missed that. In a way this felt like part three of a novel to me, and not a series, perhaps because I have read them all straight through without a break. At the same time though, this could almost work as a stand alone. You don't actually need the prior knowledge of Gen in the previous books, you can begin to understand him through the eyes of Costis.
In the previous novel, the Queen chopped of Eugenides right hand when she captured him in her palace. By the end, they had declared their love for one another and Eugenides will become the titular King.
This story picks up pretty much where the last one left off. Eugenides doesn't want the throne, he just wants the Queen. He comes across as idiotic, uninterested in the running of the country and unable to control his own scheming attendants. He is vain and rude and nobody can believe he is married to an older and taller Queen, one who cut off his hand!, through anything other than his desire to be King. Costis unfortunately punches the King in the face as, like everyone else, hates the new King. Instead of being hanged, he is forced to be at the King's beck and call. It starts to get interesting here as Costis slowly realises what the reader already knows: Eugenides is much more than he appears.
It's a convoluted plot, made more interesting when you already know Gen. But, as I said, it would work as a stand alone and a new reader would begin to understand Gen as Costis does.
Gen is still as fantastic as ever, if not more so. It becomes clear just how clever he is as his plotting and subtle manipulation begins to win over Costis while slowly overthrowing his haters. They are not friends but Costis develops a grudging respect for him, and Gen for Costis. He still managed to surprise me. He'll probably still manage to surprise me in the fourth book.
Costis is also a brilliant character. He may hate the King, but he plays no part in the tricks others are playing on him. His conscience is even wrestling with itself to tell the King who is behind it all. I liked that aspect of him, he may hate the ruler but he is willing to do his duty for him.
The ending of this novel is just fantastic, MWT really does know how to finish a book.
