Halla has had a rough life and when her father-in-law, whom she was taking care of and living with in his house, passes away things get even worse for the young widow. Because, despite inheriting the estate, she also has to contend with his greedy relatives. Fortunately, she stumbles upon a magical artifact in the house, a sword which has trapped inside a Warrior sworn to protect the wielder. 

This slow- burn romance had all my favorite tropes in it but the plot was too long and really rough in a lot of areas. You can tell the author is world building for a series with the set-up of important side characters and the HFN ending is your other clue there will be more books. 

Do not skip the content and trigger warnings for this book because the author has dark humor regarding a few sensitive topics, like suicide. 

The main characters are delightful, kind, and a bit snarky. I adore Halla's ability to weaponize questions and the way Sarkis respects her quickly, especially once he gets to know her. (Things do get spicy, though it's not the main focus.) Zale and Brindle are also stars of the book, in spite of their official status as support characters.

These main characters contrast with the various villains, who suffer from a severe inability to take interest in the perspective of others, each in a slightly different way.

The plot is both character- and setting-driven, in the manner of a campaign run by an excellent game master: some things happen not because the characters make them happen, but because things like this just happen here, and they might as well happen now. (To be clear, these events serve the plot or character arcs and I love them.) I'm thinking of the Vagrant Hills, especially, which are

a piece of geography that grabs travelers if they feel like it.

The Motherhood priests probably also qualify. 

As you'd expect in a book starring a magic sword, the setting has plenty of magic, which follows definite rules (though the characters don't know all of the rules and sometimes have to figure things out as they go). There are horrific mechanics to some of the magic and magical creatures, though I would not say this is a horror book. 

(If you plan on reading this book, please make sure to look at the content warnings, as it opens up with some really heavy topics right out the gate!)

While there were some aspects of the book and romance between the main characters that weren't for me, I genuinely enjoyed it! The narrator of the audiobook does a great job with the character voices though, that really stood out to me - especially Sarkis! Du be warned though, if you do listen to the audiobook version, that this book has a few 'spicy' scenes in it. Those generally catch me off guard in audiobooks, so I thought it might be helpful to others if they knew beforehand.

Spoilers for the end of the book ahead:

I loved the last fight (in chapter 56-58 I believe?) so so much! Halla's role in general over the ending chapters was great and the dynamic between her and Zale adds so much, too. :)

There were many parts that sort of flew by that could have been expanded on and Sarkis’ past didn’t really get enough detail to disturb me at first so I would have loved if that had been expanded. Still, this was an amazing book and was very amusing and fun! I love the characters, especially Zale and Halla. I wish Brindle could’ve gotten more time to shine but ultimately I think it just would’ve slowed things down. 

There’s a minor character who seems to be ace and it’s not treated well but not for discrimination reasons, just for horny reasons. Still, as an ace person, it put a damper on the book but it was a very minor part and there was some great nonbinary representation.

Spoiler-free review

This is not a 5 stars due du personnal preferences, but as far as its genre goes, it definitely should be !
Note : this is my first T. Kingfisher book, and it's interesting to see references to other books (Clockwork Boys), but it never felt like I needed to have read those beforehand.

Swordheart is a lighthearted and wholesome romance aventure that never stops to be interesting. I got really attached to the characters thanks to their inner monologue and quirks.
It would be easy for a hetero bodyguard type of romance to fall in the trope of "damsel in distress", but I felt it was well handled : while the warrior bodyguard is indeed experienced and efficient in any martial situation, we discover that the female main character has her own ressources and strength that shine in other situations. All of the main characters had strength and weaknesses, and felt very human and caring.
And there is depth in the emotions and struggles of the main characters, nuancing them quite well !
The culture contrast between the two main characters led to very interesting considerations too, especially about the women's condition in Halla's (female main character) country !

A slight warning : for those romance fans who prefer an approach based on emotions only and would prefer little to no mention of physical attraction, be aware that this is a romance between two people who are very much physically attracted to each other (not only, definitely), and it is explicitly told so ! (It was an interesting ride for my asexual mind lol). If you're unsure about sex references (very minor spoiler) : 

expect two sex scenes, explicit but not too detailed, consensual and between people who are very much in love with each other. Expect also some mentions of genitals and physical reactions to a loved one, but it's in no way overwhelming (take that from somleone who has very low tolerance about that matter)

I felt that is was well done, being respectful and wholesome, and adressing the hardships of being attracted to someone, so even if it's not what I am used to, it felt right. Sarkis especially (the bodyguard) is a very respectful man, aware of his strength and the dominant position he can have through his bodyguard role.

The side characters finally were intensely loveable : I'm joining the crowd of the gnoles fans (Brindle here at least is a very good fellow), and I really loved one of main secondary characters, who is a non-binary person (they just are, no plot related to this fact : they exist in this world as everyone else and it's very comforting). I got really attached to them and their friendship with the main characters were a highlight of the whole book to me.
