Another awesome stand alone action/adventure by Aussie author Greig Beck! I love his books! Especially on audio narrated by Sean Mangan! Like an action movie for your ears!

Cate Granger is an evolutionary biologist, intent on following her grandfather’s footsteps, who disappeared in Baranof Island the Gulf of Alaska, back in 1952. With a team of fellow scientists, a billionaire, and an old flame, Cate makes her way by submarine into an untouched underground sea. They soon find they are n

Cate Granger is following in her long-lost ancestor's footsteps in more way than one. Her fascination with the unknown deep is one shared by her grandfather, who mysteriously disappeared long before her birth. Along with a crew of eager scientists she descends upon Baranof Island, in the Gulf of Alaska. Or, more accurately, the self-contained underwater cove that had been preserved there. As she descends she finds the clues to her grandfather's disappearance that has haunted her family. But, alo ...more

In FATHOMLESS, Greig Beck delivers a Hollywood type thrill ride with the technical and scientific backing to help carry the story. Not a bad read, but personally I think Steve Alten did the Mega shark tale better in his novel, Meg. The most disappointing thing about FATHOMLESS is the unforgivable editing. There were dozens of errors and omitted words throughout the entire book, which was distracting and quite annoying. In his ACKNOWLEDGEMENTS section, Beck profusely thanks his editor and all I c ...more

10* Fave!

This was the best sea & subterranean creature feature I've read in a long time! It was a non-stop thrill ride from beginning to end. I was dragging out the pages just because I didn't want it to end.

I asked my husband the other day, "What would scare you the most; exploring outer space or exploring the deep ocean?"
I love the ocean...I find it peaceful, calming, and quite beautiful and powerful. But, the thought of exploring the deep ocean, I must admit, I find quite terrifying. Probably because it's part of our home and the thought of huge terrifying creatures living in it gives me the heebie jeebies.

This book filled me with dread. Just the thought of something that big coming out of the w
The concept of this book wasn't terrible: a warm, underground sea filled with amazing and terrifying creatures. Unfortunately, that part of the book is over in the first half. After that, it's less Creature Feature and more Making Bad Choices On the Open Sea.

The romantic subplot was odd and forced (who doesn't want to make out with their ex in a pitch dark cave, in front of a third party, while being hunted by a giant shark?). The characters would have been perfectly safe had they stuck to water

Oh. My. God. This book was absolutely phenomenal. I was sucked in right from the start and as an avid horror fan I’ll admit I had the willies. Reading in bed I made sure I had no loose limbs hanging over the end as if the Meg would magically appear under my bed and pull me under. I should mention I’m 34 😂😂. If there is one thing I fear more than anything it’s open water and what lies beneath. I absolutely 100% hate sharks but I can’t not read or watch whatever they star in. While I typically wat ...more

Subterranean sea closed off for millions of years and supporting prehistoric sea life. This part was cool, as it piqued my interest to do a little research on these now extinct creatures. Good thing too! These were truly terrors of the deep, making our present great whites nothing but Nemos. Okay story - it had the sea creatures, adventure, cold-blooded sexy killer Russian, the Megalodon that was released into the Pacific, and lots of yummy people snacks for it. The weird thing is the story tell ...more
In honour of Shark Week, I picked up Fathomless - a new deep sea thriller featuring no other but C. megalodon. I was so excited! To be honest, I did not expect literary genius here, but rather an action-packed adventure with lots of bigass sharks chomping on unsuspecting humans. While I did get kind of what I was looking for plot-wise, I really REALLY hated the characters.

Unfortunately a lot of the action was narrated through the dialogue, which was not one of the book's strongest points. To be

Fathomless is a gold ole fashion adventure read with monsters from the past trying to gobble everyone up. Grieg back has managed to meld together a whole heap of sub genres to deliver a Hollywood blockbuster worthy story. The story, characters and surprisingly the science are all good and mix well with the fast pace action to keep the reader on the edge.

This was a well-paced, interesting horror novel. Simple, yet effective.

I really wish Beck would have just stayed in his ‘fiction lane’. In ending the book with laughable conspiracy theories, that posit the Megalodon could still roam the oceans, I completely soured to the entire book. Did we not learn enough from Peter Benchley’s mistakes? In blurring the lines between realistic shark behaviours and some fantastical representation of the species, Beck contributes to the undeserved reputation of s

A subterranean sea filled with prehistoric terrors lies under the frozen Alaskan tundra. A team of scientists, bankrolled by a very wealthy eccentric man, go on an expedition to find the primordial place and to bring back news of it to the world. This was a really well written creature thriller! I will definitely be checking out Greig Beck's other books.

I have read every book that Greig Beck has written so far and I had been very much looking forward to reading this one too.

As usual, this is a mixture of adventure, horror and science fiction and yet you very much believe that the scenarios that Mr Beck describes can absolutely occur. There is always a thread of fact running through his books, which is why you end up at the edge of your seat whilst reading this and his other books!

Compared to some of his other books, this one didn't grip me qui

I enjoyed this one. Cate and her fellow scientists, along with a Russian billionaire, and two crew explore an undiscovered cave, hoping to find a new species. They are underground in a small submarine and are attacked by a giant shark - Carcharodon

Totally loved this book about the search for hidden information in the depths beneath. I loved the intro where Beck outlines that we know more about the surface of the moon than we do about Earth's ocean.

This is a totally fascinating read about what can happen when we go meddling in the great beyond beneath. Just what ecosystems will we disturb and more importantly unleash. This tale was a nail biter from start to finish with a bit of romance mixed in for good measure.

The good: the initial premise is good. Prehistoric creatures have survived in a huge underground area. Our heroes start out exploring and things go wrong. Trapped in an nearly endless sea in an unclimable cavern... with huge monsters. Genuinely creepy stuff.

The bad: the rot starts early in what is an otherwise competently written, language wise, book. The prehistoric creatures are ones well known to anyone who has a vague interest (which beggars belief as it'd be more likely we'd never have eve

Yikes! Fathomless is a truly scary, dark water tale. And by dark water, I mean underground sea, millions of years old. Natives call the place Bad Water and with very good reason. When you hunt the deep unknown, you become the hunted.
I love the tension between characters, the bravery, the sacrifice and the double-crosses. The scary creatures of the deep are pretty awesome, too.

Wow, what an adventure a thrilling tale, full of action, monsters of the deep and a new hero Jack looking forward to his next adventure.

The first book I finished in 2019 was Fathomless. I do consider finishing this book today a little bit of a cheat to count it towards my 2019 read books list since I started and read 89% of the book in 2018, but watcha going to do?

After watching The Meg, one of those good bad movies I love to watch, I kind of felt like staying with the shark theme when I picked out the next book I was going to read. Searching around the Amazon store on my Kindle late at night, I stumbled upon Fathomless by Greig

So here we are again, reviewing a Greig Beck book and this time featuring one of my favorite creatures of all times: the megalodon. Ever since childhood and my friend started telling me about this shark that could swallow five humans whole at the same time (when I was already deathly afraid of sharks), I've been equal parts terrified and fascinated by this monstrous animal.

These days scientists don't think it was quite as big as reported once, something to do with how they placed the teeth and t

If you’re looking for a fast-paced, edge-of-your-seat thriller starring none other than a giant shark, then FATHOMLESS is the perfect escapist read. Evolutionary Biologist Cate Granger is in search of answers to her grandfather’s disappearance years before and heads to Alaska in search of an underground sea. She and her team find more than they bargained for, and it should come as no surprise that the shark escapes back into the ‘real’ world. This is ‘Jaws’ and ‘The Meg’ and ‘Sharknado’ all roll ...more

I think I prefer the Alex Hunter books but this author is consistently good (and I love the narrators voice). Action, suspense, science.
Jim is exploring a Nantouk legend that tells of young men going into the Bad Water to battle a monster and prove themselves to be men and bring home a trophy. He believes he has found the route they took and finds himself in a series of caves but an accident with his lantern leads to him finding out exactly what is in the Bad Water. He is never heard from again. Now years later his granddaughter Cate is following in his footsteps and is about to find the caves and a hole leading down to an under ...more

Adventure novels are sturdy creatures that find themselves lounging on bookshelves, being read at the beach, and pretty much enjoying strong sales at the book stores. They are generously docile until the reader starts rifling their pages. At that point they have a tendency to hook their claws into you and you are pretty much stuck with them until the last exciting page.

Greig Beck is an Australian writer who knows the adventure thriller quite intimately. He seems to revel in them. This new creatu
