After the big cliffhanger at the end of A Kingdom of Flesh and Fire, I was really looking forward to this book. However, by 400 pages in I was ready to tear my hair out. It's a slog filled with repetition and a lot of journeying around and going nowhere in the plot. At that point, I was thinking that there's a lot to wrap up and I discovered that there is more book(s) after this (I'm not sure how many). Considering that I would have cut out about 2/3's of this book, I just about had enough of poor Poppy and her 'am I good enough' routine. I toughed it out and I'm glad I did because the author really redeemed herself with the big cliffhanger ending again. I'm not sure if it's enough to make me continue the series, but it was much better action and plot movement. I wish more was given to Cas to do than have sex with Poppy and tease her about Miss Willa; he seemed to fade into the background in this book which was disappointing to me. I'm not all about THE CHOSEN ONE trope, and it was more than emphasized here. A tight edit cutting out the fat and repetition would have done a lot to make this book better.
