I really enjoyed this book, second of the Goddess Test series. It was a good follow-up to the first book and offered many surprises. The world building was excellent and I loved learning more about the Underworld and how things work within that realm. I also found it extremely interesting learning more about the different gods and goddesses and what some of their individual talents and gifts are. Throwing a powerful Titan into the mix was a great idea, and learning about why the gods and goddesses were made in the first place was intriguing. 
 The one thing that caused me to not give this one a 5 star rating was how irritating it was that Kate and Henry were so in love when she left Eden Manor in the first book, and now that it's autumn and she returns to the Underworld to be with him again, it's like they never had feelings for each other at all. Of course, Kate is expecting everything to be like it was when she left. Henry, however, is cold and standoffish, and just, in my opinion, rude. It aggravates me that the majority of this book takes place with us having no idea how their relationship is going to progress, if they will be together and in love, if they will be together but unhappy and not in love, or if she will leave and he will fade. It's nonsense! But, since there are a lot of other things going on throughout the book that cause them to not be able to spend time together, I only am taking away one star for that. 
 The ending of the book is a cliffhanger!!! Oh my goodness, I can not believe the ending!!! I can't wait to find out what happens next so I will definitely be reading on in the series. Great book, and so far a great series...highly recommended. =)
