The book was enjoyable and well written, decent entry in the series EXCEPT for 2 plot points that almost ruined the series for me.
1) the first 3 books kept mentioning the orc raids, they killed his brother, raiding and pillaging villages and made super dangerous hybrids and then in this book the raids stop. The MC, instead of thinking something is up, breathes a sigh of relief thinking the problem went away and after dealing with the ice giants he'd have a moment to relax......uh no, that's just ignorant.
2) Madeline. Was not a fan of her character in the last book and this book did not make her any better. She is a walking red flag. Her loyalty to the MC is uncertain, her motives are unclear and is a character with questionable morals. There are multiple reasons why the MC and her being in a relationship are a bad idea....he's going to be the ruler of a country, she is NOT a good person to give any sort of authority or power to. Those are my reasons for why she's a terrible LI for the MC, but what ruined the book for me was that instead of the MC thinking about any of this, or resolving the issues around her loyalty and commitment, he instead thinks with his dick and enters into a physically intimate only relationship with her. A man who already has 4 dedicated women who have each committed to marrying him and his family, "temporarily" adds in another woman to his rotation that could harm this dynamic. It just rubbed me the wrong way, because the MC has 4 woman.....he is not lacking for sex, so adding in a 5th who is just there for sex paints the MC as greedy, immature, and inconsiderate.
