Monster. Vicious. Alone.

All Aya Sinclair has ever known since the extermination of her people is that no one can know her secret, or she too, will follow them to the grave. At sixteen, she’s made a name for herself in the Dusk Quarter but at a price.

Her latest mission ought to be a simple one, but a chance discovery will alter the course of her life—
forever. Now, she must do what she has never done before—trust a stranger, forge a bond, and her carve out the home she never thought possible.

For the last necromancer, it’s time for a little carnage.

I am both happy and sad. Happy because I was able to enjoy another piece of Purgatory Chronicles, sad because it's over and the only thing left for me to do is do a reread.

This novella allows you to have a greater isight on the relationship between Aya and Sabra. It answers clearly to some of the questions I had regarding the duology.

It can be easily read both before and after the two books without causing confusion, allowing even those approaching this series for the first time to understand without problems.

In this prequel fantasy novella you will find:
- feminine rage
- revenge
- trauma bonding
- found family
and the start of what will become a beautiful friendship between a Necromancer and a Demon


CW: violence - mention of mass murder - blood and gore - captivity - torture (off page) - child death (mention) - alcohol consumption by a minor - decapitation

This was a story I didn't know I needed.
After reading a Ballard of Betrayal and A Song of Death this answered questions and gave us an insight to a young Aya.
Just like the other two books, the author delivered action, sass and banter that had me giggling and laughing.
The story drags you into world immediately and after being here before, I felt comfortable where I was at.
The old shack/cabin, the paranormal characters of purgatory keep you intrigued and turning the pages to find out more.
Thoroughly enjoyed this.

I love the Purgatory Chronicles, so knowing that the world will continue beyond the duology makes me very happy.
This prequel is about Aya and Sabra, the way they meet and how their bond forms, and is written in such a way that someone unfamiliar with the duology could easily follow the plot.
Overall, I loved this book- the characters are still amazing, the pacing is great, all with the sass and banter that I expect from this series.

This was my first foray into the world of Purgatory but was it a good one. Having not read the duology it was still very easy to follow along with the characters and world.
I'm not sure who I loved more out of Aya and Sabra, Aya is similar to a more badass slightly more unhinged Aelin from Throne of Glass and Sabra went through some horrible things but it still caring and optomistic (and will also kick your ass). It was easy to read, definitely a nice book to cozy up with!
