Seven years ago, the Atargatis set off on a voyage to the Mariana Trench to film a “mockumentary” bringing to life ancient sea creatures of legend. It was lost at sea with all hands. Some have called it a hoax; others have called it a maritime tragedy.
Now, a new crew has been assembled. But this time they’re not out to entertain. Some seek to validate their life’s work. Some seek the greatest hunt of all. Some seek the truth. But for the ambitious young scientist Victoria Stewart this is a voyage to uncover the fate of the sister she lost.
Whatever the truth may be, it will only be found below the waves.
But the secrets of the deep come with a price.My thoughts:
I love mermaid tales. Not all admittedly have appealed to me but this one really peaked my interest. It is horror so no singing red haired girl longing for legs (although that original Grimm tale could also be horror). It also spoke a lot to the horror of what humans have done to the ecosystem. Now this isn't a book on questioning who is the villain in this tale, as the mermaids were presented as nothing but killers... but there is an opening and this theme may come into play in later books. There is also a working knowledge of science and even the holes in biological science that has yet to be filled. This lent the book a realistic feel and you could believe that these monsters could exist.
While this is a horror tale, those who like romance will get a taste of it, but only a taste. We tend to be more engaged in why they came aboard and how they change as things start happening. The horror of what the sirens (mermaids) wrought take center stage and any more romance would have muddied the waters... so to speak. There is an opening for further romance and I think it may happen more as the series progresses.
We also journey in this tale through book excerpts from the experts on the voyage as well as diary quotes and other mediums so the tale gets broken up a bit but it enhances the peril these voyagers found themselves. This also made the tale feel unique as well.
I give this book 4 stars. If you are looking for a good horror tale, I do highly recommend this book. While the book falters a bit in the end for me, it still feels complete with open threads to be explored as we learn more about the sirens of the deep. I also really appreciated how the science was used successfully in this book.
