This book was a lot of fun! It was definitely unique for me, I've never read anything like this before. I liked the characters (Stephen Day was so freaking adorable and Lucien was pretty hot, also I really liked Merrick?) 
 The plot was really intriguing, I wanted to continue reading to find out what was happening and who was causing all of the trouble. It was definitely a darker read with evil magic and some dark characters, but I did really enjoy that aspect of it. 
 However, I did feel that it got a little too much in parts, there was one point where there were so many secondary characters' names that were mostly irrelevant tossed about that I could hardly keep up with what was going on. I also feel as though I would have benefitted from a better description of some of the magic system and how magic actually worked, especially towards the end as the climax built up, as it did get a bit confusing to me. 
 I did enjoy the relationship between Stephen and Lucien, and the bond that Lucien and Merrick had too. They were strong, different relationships that I really enjoyed. I liked the setting and the descriptions, they were written brilliantly. It was just enough description to give me a detailed picture of the scene in my mind, but not enough to bore me and make me want to skim-read. 
 This book was dark, fun, exciting and different, and I did really enjoy it, but it wasn't anything amazing. I don't think I'll be picking up the next book straight away, but I may do in the future. I feel as though this story is lacking in something for me, I'm just not entirely sure what. It was a good book, but nothing is making me want to pick up the sequel, so we shall see!
