‘Angel of Death’ is phenomenal. The writing is snappy, the dialogue is well-crafted, and the character growth is just *mwah* chefs kiss.
Jere grows throughout the entire novel; there is hardly a chapter where he doesn’t learn something new and integral to his development. His powers are well-thought out and executed well, and his mechanical personality is quite fun to read.
Ylfa is great too; I love the way she brings out Jere’s feelings slowly, and the way she gradually teaches him to allow his emotions to show. Her personality initially doesn’t seem like it’ll mesh well with Jere, but it soon becomes clear just how well they play off each other.
The action is perfectly suited to the story. It doesn’t overstay its welcome and gets the job done, leaving more room for the characters to develop and grow, which, in my opinion, is the main focus of the story.
In effect, nearly everything that ‘Angel of Death’ sets out to do, it does with amazing skill.
The things that are important to the story, i.e. the characters, their relationship, the world and towns around them, are all written expertly.
Adding onto that, any questions about the story that I had were readily answered by the author and made clear to me.
Go read the story now; it is well worth your time and the character interactions are both charming and well made!
Go Jere!

So… Why Only Four Stars?
(HEAVY SPOILERS AHEAD)
Because of chapter 22 and the consequences of it.
In chapter 22, Jere explodes and kills an encroaching enemy army that threatens to kill him and Ylfa.
This power comes out of nowhere.
This explosion doesn’t hurt Jere, but it does have lasting effects on Ylfa.
The issue I have with this is that not only does Jere use a previously unheard of ability to win a fight; him doing so has lasting consequences on the story that are far reaching.
What comes after that chapter is no less well-written than what came before, but since it all stems from that chapter and the consequences of it, I can’t enjoy it without thinking: “Why did things happen this way?”

Of course, I encourage you to read this story and form your own opinion!
