I love and hate this book so much. And for that reason it is now my favorite of the series. This book had me in the feels constantly. I went through so many emotions throughout. At one point I'm pretty sure I felt like ten emotions in like two pages. I really enjoyed this one. It starts out giving us more background into the Elena and Gavin war with Erawan. I enjoyed the different perspective and the background because it felt like the perfect time to get to know more. I liked seeing more connections to that generation and our current group. 

All the main players experience some dramatic shifts in this one. Elide is still making her way to meet Aelin and she has an insane journey to get there. Manon and the Thirteen experience some insane moments I didn't see coming; she is going to face some intense repercussions for her decisions. Aelin is forced to face some hard truths about becoming queen. A lot of this one is Aelin and group trying to find the third key and follow the new instructions to search for something called the Lock. All while our dear sweet Aelin is trying to find a few alliances to fight with them against Erawan. 

The number of shocks this book gave had me on the edge of my seat the entire time. Aelin is still her scheming self and I love it. She is clearly working on something and each time we get the reveal I am shook. My brain could not handle all the information I was getting in this one, because it was just one "oh my god" moment after another. Once they were revealed they made perfect sense. Each one was either beautiful or devastating. I don't think I will recover from this one anytime soon. It was just so amazing.
