This is a well-written, eerily suspenseful novel. The author switches back and forth between the present and the past in every other chapter until the mystery is finally revealed at the end. This is a dark and tragic mermaid story that also involves some magic and a few ghosts. Not really my cup of tea (hence the 3-star rating, not because of the writing or story itself), but if it is yours, then this is the book for you.
