Book Review: Into the Drowning Deep by Mira Grant

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.


Mermaids are real. They are dangerous. And they are very, very hungry.

I really loved the 2015  novella Rolling in the Deep (review), so I was thrilled when I learned that a full-length novel was to follow. I was also a little nervous — the novella was so perfectly constructed and so utterly disturbing. Could the novel live up to the promise of the novella?

The answer is a resounding yes.

Into the Drowning Deep picks up seven years later, when the tragic loss of the Atargatis is remembered as a personal devastation by some, and derided as a hoax by many others. Imagine Network, responsible for the first voyage, is determined to redeem its less-than-respectable reputation and commissions a huge, elaborate research vessel to go back out to he Mariana Trench and find proof that the events shown on the found footage from the Atargatis were real. The new ship, the Melusine, is filled with top scientists and researchers in fields of oceanography, oceanographic acoustics, marine biology, organic chemistry, and more. It’s also staffed by Imagine’s corporate henchman and the network’s quirky/geeky/adorable TV personality, who’s there to record everything that happens for the sake of the inevitable documentary to follow up on the voyage.

My first thought as I read about the Melusine’s voyage: Are these people nuts? Everyone from the Atargatis died, brutally, eaten by sea creatures with big sharp teeth and a hunter’s instinct for tracking down prey. Why on earth would sane people intentionally choose to go back there?

Well. Science. Vengeance. Money. Fame.

The mystery of the creatures caught on film on the Atargatis is simply too alluring to resist. The scientists all dream of prize-worthy glory, seeing the new voyage as a chance to prove the existence of an unknown species, to find something truly new and introduce it to the world. And there are those with personal stakes as well, including Tory, the scientist whose sister Anne perished seven years earlier and who has been chasing her sister’s shadow for all the years since.

Let’s just say that pretty much what we knew would happen, happens. Yes, the mermaids attack again — but this time the people are at least a little more prepared than the first time around, and although the bloody mayhem is intense and brutal, there’s also progress in understanding more about the nature of the creatures — what they are, how they function, and even the rudiments of how they communicate. It’s all quite brilliant — bloodily so.

I love Mira Grant’s writing. She manages to create interesting characters — some to root for, some to despise — and then throw them into situations that challenge them, threaten them, and cause them to either rise to the occasion or be consumed by their own worst character flaws. And yes, “consumed” is an appropriate word, since bad decisions quickly lead to becoming mermaid chow.

One (of many) brilliant aspects of this book is that it’s set just slightly forward into the future, but not by much. The action takes place in 2022, and the author paints a picture of a world already feeling the ugly effects of climate change. The changing ocean temperatures and resulting changes in the ocean ecosystem directly influence what happens in Into the Drowning Deep. It’s not preachy, just presented as inevitable result of the direction we’re heading in now. Definitely provides food for thought, and should make us all pause… and worry.

While the ending was rich and satisfying and edge-of-the-seat suspenseful, I think the door is open for the story to continue… and I really hope it does. I want more! I want to see what happens next with the characters left alive at the end of the story (definitely fewer than there were at the start!), and how the world chooses to deal with the mermaids now that their existence is proven beyond doubt.

Reading this book gave me chills, in all the best ways. A few tidbits for your reading pleasure:

Had they looked, they might not have seen anything. Daryl was inexperienced compared to Gregory, and more, he was letting his nerves get the better of him; he was seeing danger in every corner, and allowing it to blind him to the danger that was actually lurking. He would have seen the smooth sweep of the hull, the fruit of human labor and innovation, intended to protect them from the dangerous waters. He would have seen how high up he was, and how far the mermaids would need to climb, and felt this rendered him safe, somehow. Protected, sheltered, like a small fish choosing to believe the coral reef can offer genuine protection from the jaws of the eel, the arms of the octopus.

(The door would not protect them; the door was not enough. The door was wood and riveted steel and it was not enough. Tory had known that even before they’d run past the first shattered door. The cabin beyond had been dark, but not dark enough; there was blood on the door, and blood mixed into the slime onthe deck outside, and none of them were safe. Not here, not anywhere.)

Do I think they found mermaids?

Yes. Of course I do.

And I think the mermaids ate them all.

And finally, one from the perspective of the mermaids:

Where there was one of these things, there were always others. The delicate, delicious things that died so easily never traveled alone. Their schools varied in number from few to many, but they never traveled alone.

Deep beneath the waves, the hungry turned their eyes upward, toward the promise of plenty, and began to prepare.

  2. I loved Rolling in the Deep too! It was SO creepy! I also started Into the Drowning Deep. I got to about 30%, laboriously, and felt like nothing was happening at all. I ended up putting it down again and reading something lighter. How far in would you say it starts to pick up?

  3. I never thought I would be interested in mermaid horror but this sounds amazing! I’ve read and liked Mira/Seanan’s writing before so this is an easy add to the TBR.
