About this book

A man possessed. A witch who is determined to save him. And a demon who will stop at nothing to claim them both.

Ava Helacourt has never met a demon she couldn’t exorcise. Outcast amongst the other witches in her coven and estranged from her own family, Ava only finds solace from her dark past in her studies as a demonologist to protect the mortal realm from the monsters that creep in through the rifts between the two worlds.

When Rory, a man possessed by a demon who calls himself Vain, is captured by her coven, Ava throws herself headfirst into untangling the web surrounding the two of them. Even when Rory seems to have lost all his will to fight back against the demon who refuses to leave his human vessel, she is determined to free him from his lustful and tempting captor.

But as the lines between human and demon begin to blur and it becomes clear that their connection is deeper than she initially realized, Ava starts to question everything she has ever known, and must decide how far she is willing to go in order to save Rory’s soul. Even if that means ruining hers in the process.

A Study of Blood and Ichor is a dark and sensual MMF paranormal romance with heavy themes and mature content. Readers are encouraged to read the authors note in the front matter for a full list of content warnings.

Holy wow. I am blown away at how much I really enjoyed this book. It would have been a 5 stars but I did find myself struggling with the FMC a bit.

I read this in one day. I didn't want it to end! The character art sold me, but the writing had me staying. This was a solid read for spooky vibes. I want more in this weird (in the best way) alternate world Katia has created! )

Solid debut

August 27, 2025

A STUDY OF BLOOD AND ICHOR immediately caught my attention with it's premise: a witch trying to exorcise a possessed man and falling in love with both the man and the demon? Sign me up! The world-building was on the light side and I would have liked to understand more about where the world was now that demons and witches are known to humanity, but for a debut book it was really solid. There is some plot going on but the bulk of the book was focused on the budding relationship between our witch...

Great plot and character building

This book was a great mixture of spice, sadness, vulnerability and love. I enjoyed how each character interacted with one another and the end was *chefs kiss* everything I had been wanting. )
