I thought this book was very good. I have been a huge fan of Amanda Hocking for a long time now, and have read all of her books. So, when I found out about this new series, I was super excited. I figured it had something to do with mermaids/sirens- which is a genre I'm kind of new to- but I thought this was a very interesting twist on the genre. I found the entire book extremely interesting, and very well written. I honestly couldn't put this book down! While there are alternating perspectives, sometimes paragraph-to-paragraph, I didn't mind it that much because it flowed well and made sense. 
 The only thing I didn't like is that some of the characters didn't seemed as developed as others. I just wanted a little more information/time with those characters. Nevertheless, I loved both Alex and Daniel, and hope that Daniel and Harper get together because she really needs somebody like him. I also think that there is more to Daniel than meets the eye because he seems to know something, but we must wait and see. 
 Be prepared, the story cuts off right at the climax of the book! Obviously, this is a cliffhanger to keep us coming back for more, but I would have liked a little more haha. I can't wait to see what happens next because I already know that this is going to be another fabulous series from Ms. Hocking!! I definitely recommend this book to everyone who is into the mermaid/siren genre, but also for fans of Amanda Hocking. You won't be disappointed!
