I loved House of Hollow and I was ready for something similar so I was excited to see this author had another one coming out. This book was nothing like that, but it was wonderfully dark in its own way. I did think this one took longer to catch my interest but once it did I was swept away in this world of demons. I loved the idea that only women can bargain with demons to gain the power inherently denied them. The characters were all a bit flatter than I was hoping and I didn’t get as invested in them as I wanted to be, but by the end I felt they were fleshed out. Zara and Jude are both searching for a witch for very different reasons. Zara wants to bring her sister back to life so she can apologize for some stupid things she said. Jude accidentally tied a demon to herself poorly and it’s killing her so she wants the invocation removed. When they meet Emer they a re thrilled as they are sure she can help them, but the three of them are soon distracted by a serial killer who is hunting demon bound witches for their power.
