I was given this ARC by the publisher via NetGalley in return for an honest review.

Artimesia, a girl previously possessed as a girl, is training to be a nun who cleanses bodies of deceased so their souls can move on. If souls remain with their bodies, they become something destructive to the living. After her convent is attacked by possessed soldiers, Artimesia awakens a spirit of the highest order and must work with it in order to save the world.

This book surprised me with how much I liked it! There were definitely some slower parts, but it was so interesting and different from anything else in the YA category right now. I loved the Revanent character, and the main character, Artimesia, was so interesting, and again, not like other female leads out there in the genre right now. I loved the way the Revanent and Artimesia worked together, and their whole relationship. The magic in this book was so awesome. It definitely kept me interested and made me think and question things. I will definitely be purchasing this when it is released! 4/5 stars.
