Summary from Goodreads:
Fate isn’t something to mess with… and now, neither is Alex.
Alex has always feared two things: losing herself in the Awakening and being placed on the Elixir. But love has always been stronger than Fate, and Aiden St. Delphi is willing to make war on the gods—and Alex herself—to bring her back.
The gods have killed thousands and could destroy entire cities in their quest to stop Seth from taking Alex’s power and becoming the all-powerful God Killer. But breaking Alex’s connection to Seth isn’t the only problem. There are a few pesky little loopholes in the whole “an Apollyon can’t be killed” theory, and the only person who might know how to stop the destruction has been dead for centuries.
Finding their way past the barriers that guard the Underworld, searching for one soul among countless millions, and then somehow returning will be hard enough. Alex might be able to keep Seth from becoming the God Killer… or she might become the God Killer herself.
I really do like this series as a whole so I couldn’t wait to read this book after the cliffhanger in the third book.
Honestly I feel that this is the book where everything slows down right before the big moment. This book is about showing you how Alex has changed in small ways and what she is looking for in her life at this point. It shows her needs as a girl who is really growing up and understanding the world around her that much more. Alex was a little immature when this series first started but I have loved watching her grow and I love really enjoyed watching her figure out just what it is that she wants out of a relationship. I feel her growth in this book was what I really liked best about it. Another thing I really enjoyed was seeing more of the Gods/Goddesses. I have always loved when Greek mythology is added to teen stories so I’m really happy that Armentrout took the series in this direction. I feel the Gods have something to add to this story and I just wish that we would have been able to see even more of them.
I ultimately think that this book will bring some clarity to certain situations. The series has always gone back and for between Seth and Aiden and the differences between the two guys. I’m happy that Alex has decided where she is going with these guys and yes there are some heart breaking scenes where the two guys are involved and I really enjoyed watching every second of it unfold. I’m also really happy that Armentrout was not holding back this time. This has turned into an older teen series and let me tell you there was some steam going on in this book! I love that authors are pushing the boundaries of where teen crosses over into new adult.
Overall, I really did like this book for the fact that it did slow down all of the drama and action in order to help the characters take a pause. Sometimes characters need a break to reconnect with their surroundings in the book and with you as a reader. There were a few things that I didn’t like about this book and that had me putting down the book from time to time. Sometimes I would be right there with the characters but sometimes it was just a little too much so I would have to put the book down for a day or so in order to come back to it but overall I’m still happy with the series as a whole.
