This was my first book featuring sirens/mermaids. It was an interesting concept and the mystery surrounding the plot wasn’t too bad. The plot itself was not too bad and the setting suited the story. There was just one problem, and that was the characters. I couldn’t begin to like the characters, even if I tried. They were bland, they were uninteresting and if it hadn’t been for the plot being slightly interesting, I probably wouldn’t have gone further into this book. The supposed romance featured in the book wasn’t that great either - I suppose because the characters weren’t that interesting to begin with. The romance seemed forced, and artificial, and they both acted in a very robotic nature. The plot was in between. At times it was interesting, at other times, there’s a lull and it tended to drag. I liked how Vanessa was uncovering secret after secret regarding her sister, and the ending did make up for some of the shortfalls - although I still remain not satisfied with the way the characters were done. I will be reading the sequel to this, but am not in a big rush to go out and get it. The book was an okay read, but it could have been made much better, especially when it came to its’ characters. This is the type of book where good character creation would have made the book much better and more fun to read.
