Definitely read Ashen Dreams before reading this book, and warning I have a couple spoilers about Ashen Dreams in this review.
Requiem definitely gave a nice sense of weight, meaning, and closure regarding Ishar's death and Zethra's grieving. I feel like it really leaves the entire storyline in a great place and is a good closure to Ashen Dreams.
It convey's Zethra's sorrow, grief, and anger and will to fight moving forwards too.
I even got teary-eyed a couple times, admittedly.
The short story is also filled with all the little details I love about these books that really make the world feel alive and real.
This is definitely a must-read after Ashen Dreams.
