This is the second book in The Soul Seekers series. In this book I think we delve more into the characters themselves, into their growth and the personal obstacles they are trying to overcome. Also, into the relationship between Daire and Dace. The book is told in dual POV's which I really enjoyed. We switch back and forth between Daire and Dace which I think adds so much to how well we are able to connect with them. 
 Daire has grown so much towards the soul seeker she is prophesied to become. I sometimes ache for her because even though this is her main purpose, I still see her as a 16 year old teenage girl, struggling with love, the relationship between her and her mom, and her relationships with her girl friends, just like any other teenage girl. Before Daire moved to Enchantment, New Mexico, she had never attended public school. So having girl friends is an entirely new experience. I especially am liking her friend Lita. When Daire first started school, Lita was the ultimate mean girl. But she has really turned around. In her own way, she has become Daire's fiercest protector. I hope we get to see even more of her in the third book. 
 Dace sees nothing but his love for Daire. Dace and Daire have professed their love for one another. But, Dace has a twin bother, Cade. For everything good that Dace is, his brother equals with evil. When they were conceived, their souls were split, with Dace being everything light and Cade being everything Dark. Dace is referred to as Cade's echo. If I understand it correctly, it takes their connection to the utmost level in that whatever Dace feels can echo back to Cade. So, Cade is able to use the love Dace feels for Daire and turn it around to fuel his evil. 
 Cade has breached the underworld and is wreaking havoc on the natural balance of everything. Both Dace and Daire feel that in order to protect the other, they must be the one to kill Cade and this causes them both to put themselves in danger time and time again. When, in fact, if they had worked together they might have a better chance. 
 I am so proud of them both, though, at the levels they are willing to go to try to save one another and also their friends and loved ones. Alyson Noel does such a great job of painting such vivid pictures with her words and keeping us on the edge of our seats. The book has a huge heart attack worthy cliff hanger so I have no other choice then to go straight on into the third book.
