City of Eternal Night continues Kristen Painter's House of Comarre spin-off series. 
 Harlow is still in New Orleans having decided, after the horrific encounter with her father, to stay. She's been feeling this hollowness inside ever since her encounter with a vampire and she can't explain it. Things between her and Augustine are going well. Their attraction to one another is apparent on both sides, but they are both proceeding with caution. Harlow fears saying anything about the darkness inside her will turn Augustine away, but she really has no one else to turn to. 
 Augustine, as Guardian, is getting ready for the Fae Exemplar Krewe Ball. The Ball features a symbolic kidnapping of the Faery Queen. This time, however, the kidnapping proves to be the real thing and the ransom note that comes calls for Augustine's life in order to get the girl back safe and sound. 
 City of Eternal Night continued the story threads that were started in House of the Rising Sun. I liked City better for the simple fact that I liked Harlow a lot better in this book. She's finally starting to come to terms with being Fae. Even with the unknown facts about her powers, she's still not turning her nose up, she wants to learn more about herself, and she's giving Augustine a chance. Right there is reason enough for me to like this book more. 
 Augustine has been attracted to Harlow from the first time he saw her, but with her aversion to all things Fae, she couldn't stand him. Now, they are working together more in order to bring the kidnapped girl home and it's nice to see that he's encouraging her help, but not pushing, and he's not keeping her secluded from any and all danger. I love his devotion to her and her growing 
 Of course being Kristen Painter there are a lot of twists and turns, the issues between the Fae and the witches is touched upon a lot but towards the end it gets overshadowed by finding the girl. There is a cliffhanger ending, but it's not as bad as I made it out in my head. While reading, everything points to the resolution coming in the next book, and I'm ok with that. I guess I can say I appreciate where Kristen Painter leaves off with the characters, thinking that she could have made things a whole lot worse for everyone in certain matters (trying not to be spoilery here). 
 Overall, I like this series better than it's originator. I think a lot of the things that bothered me about the House of Comarre series (such as too many POVs) are resolved here. I'm excited to see how things play out in the last book.
