It's one of the most original debut I read in 2021. It's a mix of different genres: thriller, noir, metaphysical fantasy (don't know if exists but it's a good description).
I loved Joe and Daisy-May: they are two interesting characters, well thought and likeable. Their relationship grows slowly and I liked the loyalty and how they were ready to sacrifice themselves for the other.
The world building is great: the description of the Pen and the world beyond the grave are well done and there's plenty I would like to know as they are a new take on something that is usually described according to the Middle Age books (Dante's Commedia above all).
The plot is full of twists and turns, sometimes it drags a bit but it kept me hooked.
This book talks about betrayal, fear, despair but also about redemption and hope.
It you expect a sort of metaphysical Dresden File story this is not the book for you but if you want to read something original go and buy it.
Highly recommended.
Many thanks to the publisher and Netgalley for this ARC, all opinions are mine
