I really enjoyed this sequel to Wake. This book picks up right where we left off. Gemma has gone with the sirens, while Harper, Alex, and Daniel are left to face with the aftermath and finding Gemma. While most authors can't effectively do third person POV with alternating perspectives, Amanda Hocking handles it extremely well, and the story flows very nicely. There was never a time where I was confused or bored with the story. What I find even more amazing is that Ms. Hocking has created each character with a unique voice and personality. Sometimes when an author writes alternating POV's, the voices sound the same, but that is not the case in this book. 
 In Wake, I never felt that true connection to Harper, Alex, or Daniel, but that completely disappeared in this novel. Harper and Alex work extremely hard to find Gemma, and it was refreshing to see the characters develop into strong leads. There are a lot of tense moments in this novel, and the characters handle themselves in the way you would expect. None of the characters are these amazing, heroic people. They are ordinary characters faced with an unbelievable task, and that is what makes them extraordinary. My one complaint...there wasn't nearly enough Daniel. Even though Daniel wasn't very prominent in the last book either, I still fell in love with him. However, he isn't in this book nearly as much as he should in my opinion. Nevertheless, the scenes he is in, well let's just say they don't disappoint. He is even sweeter and more charming, if that's even possible. One of the other stand out characters...Marcy. I love this girl! In Wake, I barely registered her, but boy does she impress in this book. I particularly loved the scene where she and Harper (mainly Marcy) were discussing the T. Rex. Here's a taste... 
 My point is that nothing is unstoppable, and the T. rex wasn't as great as he thought he was. I mean, what were those little arms for?" Marcy pulled her arms back into her sleeves, so her hands made short 
 imitation T. rex arms, and she wiggled them back and forth. "What an idiot." 
 This just had me laughing hysterically (and she kinda has a point too). 
 However, this is ultimately Gemma's story, and Gemma's character grows so much in this book. Gemma is facing a constant struggle to give in to her siren nature, but she also becomes that much stronger. I loved every time she stood up to Penn, and her bonding with Thea. 
 The stand out part of this novel though lies in the mythology that Amanda Hocking has incorporated. I'm a sucker for any type of mythology, and Ms. Hocking just sucked me into the story with more about the siren curse and other such things. 
 While I really enjoyed reading this novel, there was still something missing to me. I can't quite put my finger on it, but there's just something not there. I can't wait to read the next in the series, Tidal because I love this series, and Amanda Hocking is one of my favorite authors. There are still a lot of questions that need to be answered, and I look forward to what Ms. Hocking has in store for us.
