I am so disappointed in this book. It really had potential, and a lot of it!! I gave this book two stars because while it did have me intrigued throughout the entire book, we were never really given in depth descriptions about betwixtmen, merpeople, and Down Below life. Every mermaid book is different so I like to have a good description about the creatures I am reading about. Also, the ending was so terrible I almost threw my Nook at the wall, and that thing is my life so I was pretty pissed. How can the author string us along the entire book for something that shitty? I mean Davies has us so worked up with all the rising action with Sephie and the drama going on constantly with Miranda and her surviving friends and their families. The drama was good, immature, but realistic. Very realistic to 17-18 year olds. I am also a 17 year old senior like Miranda and her friends, and instead of South Carolina, (where I have visited many times), I am from North Carolina mid-coastal region. Not sure if the author is actually from SC, but I was not happy with her description of the state. South Carolina beaches are BEAUTIFUL. I feel she did not give the island credit and if she would have really got into detail it would have made the scenery more interesting instead of just seeming like a creepy isolating island. The book was very intriguing with everything going on, I could not believe the outrageous ending. The ending made me reading the book a waste of time. If the author would have focused more on the creatures down below and that life, and less on Miranda and her bitchy friends complaining twenty-four seven, the book would have been better. I do not recommend this book, because you will ultimately be let down.
