Description from Goodreads:
The ocean is home to many myths,
But some are deadly…
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 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.
These are mermaids of the old stories, the mermaids of nightmares, the mermaids closer to sirens that Ariel. And I loved them. Or well, not them, but the story around them. Yes, as others have commented, the book is on the slow side. Keeping the suspense high at the expense of pace. But I appreciated that. I also appreciated the love in various forms (familial, platonic, queer, straight, and strained). I liked that an autistic character got to be a hero and that somehow Mira Grant made me feel sorry for an endangered species hunting psychopath (that couldn’t have been easy). All in all, I really quite enjoyed this.
