I really loved this book it was really good the best book about mermaids and under the sea life type books that I have read in a while. I really liked the characters especially Tristan,Layla,Kurt and Thalia they were really well written characters and a really well written MC. I really liked how Tristan was a really realistically written male character I really liked how the under the sea characters were depicted and his reactions to being half one of them and all of the interesting things that he learned. I like the slowly developing relationship between him and Layla hopefully that will develop more by the next book. I really liked the plot of the story it was really interesting I liked it from the beginning the story I really liked the concept there was never a dull moment. So overall I really liked this book and I will be continuing the series soon.
