Artemisia is a Grey Sister who works alongside the nuns of the convent, preparing the corpses for their final resting place. But when an army of possessed soldiers comes to destroy the one place that has made her feel at home, she is forced to use the relic of a saint to protect the monastery. 

The world building is simple but interesting, with well-developed themes of religion in that era. Although the pace is slow, we manage to immerse ourselves in this world and connect with the characters. 

We have a main character with trauma and a sad backstory, which is one of the most used tropes in fantasy. I liked seeing the consequences of her childhood abuse in the present. 
The writing was simple but kept me interested in her story from the beginning of the book. All the secondary characters were also good. I liked how versatile the revenant's personality was.

Overall, this was a good book.
