This book blew me away in how much the writing style got in the way of the story. Seriously if you are writing the kind of book that needs a map and glossary, both should be located in the front of the book. 

Anyway the actual story itself was attention grabbing enough once I stripped away all the human activities-like drinking and eating off of china-that didn't make any sense. i did really like that the mermaids had different types of bottom halfs going on. 

Mermaids were treated more like centaurs in this book with their customs and traditions either being borrowed from humans, or it being suggested that humans got their traditions from the merfolk. I liked the attempt at saying that mermaids can be found all over the world and that they tend to take after species from those waters. 

There was a glaring issue with that science wise. Certain species of fish can't survive outside of their respective climates. I would have expected this to be addressed in some way, like song-spells to help them survive or something. Since it is such a huge plot-point that they come together. 

All in all not my favorite book but I am invested in knowing what happens to the characters now, so there is that.
