Dark Tides
DARK TIDES is the thrilling sequel to DARK SANDS, finalist for the 2025 Aurealis Awards Best Science Fiction Novel - Australia's most prestigious speculative fiction literary award.
"‘Dark Tides’ carries a meticulous swell of horror, mystery, and science fiction through powerful world-building, foreboding dread, and a ruinous buffet of human emotion. A tsunami of panic, desperation, and sorrow choke every page, while the hopeful light of his central characters weaves through the marauding doom like the shimmering edge of an eclipse."

AFTER SOMEHOW SURVIVING THE LONG, DARK NIGHT, TARLO FELL TO A NEW WORLD.
Here on Alantia, things are different.
The colonists live in advanced skybases, the air is breathable, and the environment a far cry from the deadly sands of Cahros – in fact, Alantia is covered by a single, planet-spanning ocean.
Still clinging to dreams of discovering new life and hoping to prove himself once again, Tarlo volunteers to join a deep-sea expedition. Just as they reach the depths, a new discovery changes everything, setting into motion another desperate race for survival.
There’s something down there… in the deep…

Review of advance copy received from Publisher
Special thanks to the author for the ARC copy of this book, and apologies to my job for sneaking off for bits to read this since I could not put it down!
After a brief reintroduction to the world(s), we kick off right where we left off with Tarlo and crew now having to survive in the new, and just as hostile, environment of Alantia...a fully covered water world with a small beach near a copy of the mysterious obelisk that transported them off of Cahros.
The writing for the new world is just as descriptive and immersive; however, the strength of the story, just as in Dark Sands, is our characters. Tarlo and his small crew deal with grief, survivors guilt, imposter syndrome, and love in a way that's missing from a lot of novels, and, to me, that's where these books shine. There's complex expressions of sadness, feelings of abandonment, and jealousy, and the characters resolve these feelings and push through to survive.
I thought overall it's just as wonderful of a read as Dark Sands. I guessed where it was going and was happy when I was dead wrong. There's so much more left to unfold, and I can't wait to explore more of these worlds with our boy Tarlo and see where this goes next!

Hello readers and friends, I'm J.S. Harman!
For a long time, I left four-star ratings on my books. This was my way of showing that, while I invested everything I had in making them all they could be, I've always embraced the truth that I have much still to learn as an author.
After some reflection, and receiving some good advice, I have bumped these books up to a 5. They were my absolute best work at the time, and I want to pay tribute to these stories that I put my entire heart and soul into.
If you're reading this, thank you, and please know you can review all of my work with total honesty - I am just so grateful you gave my books your time and energy. Have a great day!
With love, JSH <3

4.5 star rating. ARC reader 📖
okay okay... but like Jesse you okay?
We pick right back up from where book 1 left us, some people at the original base and well... some people in a whole new... tide? 😆
It starts hard fast and even the characters are all pulled into another chaotic, heart pounding and insane encounter. Poor Tarlo, he just kinda wants to be a hero but ends up scared, hyperventilating and needing comfort. Its giving reluctant hero/chosen one with anxiety, but then ends up always surviving 🤣🤣
While this book allowed me to seriously consider Jesse's mental state it left me on edge wondering what on earth is going to happen next.
Dark Tides ended on another large cliffhanger, making me wonder where on earth two very interesting characters ended up and where Tarlo ended up too?
I enjoyed this book, easy to read, short, while had some maybe pacing where things happened too quick and some world building moments, where I kinda wanted more. But as it was quick I moved on quickly too!
A great sequel and I cannot wait for book 3!

There are books you enjoy, and then there are books that quietly take over your free time because you keep thinking about returning to them. Dark Tides was very much that kind of read for me. I repeatedly meant to stop at sensible points, only to continue for another chapter, then another. That feeling usually means a story has found the right balance of momentum, intrigue, and emotional investment, and this book absolutely did.
What impressed me most is how naturally it builds on the foundation of the first novel. The world is broader now, the stakes feel heavier, and the underlying mysteries become even more compelling without losing clarity. Too many sequels either overexplain what made the first book intriguing or simply delay everything. Dark Tides avoids both problems. It reveals enough to feel rewarding while still preserving the sense that there is much more beneath the surface. That ongoing mystery was one of the strongest reasons I kept wanting to read on.
Tarlo remains one of the series’ greatest strengths. He is simply an easy character to care about: capable without being invincible, decent without being naïve, and human enough that his choices carry real emotional weight. He feels like someone reacting to extraordinary circumstances rather than a manufactured hero built only to move the plot. The supporting cast also deserves praise, because they are more than names orbiting the protagonist. Their loyalties, tensions, and personalities give the story warmth and texture, which makes the danger matter more.
The emotional depth surprised me in the best way. This is not a book content with surface-level excitement. Relationships have consequences, fear feels genuine, and past events continue to shape how characters behave. Those elements ground the larger adventure and keep the story from becoming hollow spectacle.
I also really appreciated the decision to revisit the planet from the first novel while expanding the story to Earth. Returning to a familiar setting can sometimes feel repetitive, but here it had the opposite effect—it gave the series continuity and made the world feel lived-in, with places carrying memory and consequence. At the same time, bringing Earth more fully into the picture widened the scope in a satisfying way. The contrast between the known and the new, the intimate and the expansive, made the universe feel much larger without losing what had already made it compelling.
The ocean world setting is another standout. Harman uses environment exceptionally well. The seas, the isolation, the lurking sense of threat, and the sheer physical character of the world make it feel vivid and distinctive. It is not just a backdrop for action—it influences mood, movement, and survival. That kind of worldbuilding adds enormous value because it makes the setting memorable in its own right.
The novel's pacing moves confidently and knows how to end chapters in ways that make continuing difficult to resist, yet it still allows room for quieter moments of character and atmosphere. It never felt rushed.
Overall, Dark Tides is exactly what I hope for in a sequel: larger in scope, richer in character, deeper in mystery, and just as enjoyable as what came before. More than that, it was simply hard to stop reading—and that may be the strongest compliment I can give it.

Dark Tides is a successful sequel that expands the author's world, characters and in-universe stakes in a meaningful and enjoyable way. Once again, I liked the weaving together of multiple perspectives, especially as the story spreads itself across multiple locations. Once you pick this book up, it's very hard to put down. Incredible work!

The Darkworlds Saga continues with Dark Tides, an accessible and gripping sequel that I could not put down - one that left me wondering if I need therapy after reading, or if this book was the therapy I needed all along.. Regardless, the dynamic cast of characters and cosmic thought experiments posed will stay with me for a long time.
Many thanks to J.S. Harman for the ARC! All thoughts, opinions, and critiques are my own.
(My review contains no spoilers.)
Dark Tides begins where Dark Sands left off: our four survivors thrown into another world, one of mysterious depths and eldritch tidings. As always, Harman’s world-building was a successful blend of cinema, vivid atmosphere, and spine-chilling, ephemeral calm before utter chaos. Fast-paced, though intentioned, I only wish there were more moments of exploration of the evocative nature of Atlantia.
That being said, I loved the increased focus on horror and the ‘other’ POV chapters. The continued expansion into different worlds propelled me through, and I am eager to know how it all comes together in the finale. Where Sands was more localized and situational, Tides is just the beginning of broader implications and what the future holds for Earth and the human species.
As intriguing as Harman’s world-building is, the beauty of his writing truly lies in his characters - flawed and real. Dark Tides traverses the actuality of death, survivor’s guilt, grief, trauma, and the poignant realities of PTSD, all of which come and are explored in various presentations. I completely agree that our lovable Tarlo deserves to touch some much-needed grass in the next book!
Heavily emotional, though well-balanced throughout, my time with Dark Tides was a collaboration between philosophical theorizing and accepting that I will not have all the answers. Not to mention, the big reveal that left my jaw on the floor - as well as the subtle proposition of biological godliness and evolutionary purification - just brilliant! I need more, and someone to talk about all this with!
Unlike the psionic maw, I devoured this book, and can’t wait to read it again when the final installment arrives! Definitely for sci-fi and horror readers, though also for the ever-curious and lovers of intentional ambiguity.

Read book 1 in two days and jumped straight into book 2, finishing it within a day! The hints of cosmic horror which have been increasingly dropped throughout the series have me hooked 🪝
I’m pretty new to sci fi but this series has been a great intro to the genre. This is the first series I’ve read in a long time where I’ve actually started to care about the characters, which is something I’ve struggled with in particular for sci fi stories. The casual reveals about characters’ relationships and interests are natural, and the characters themselves are flawed realistically but are generally still decent people just trying to push through. They’re normal people who aren’t cliche characters. Even characters I don’t really care about, I still feel for? They all feel human (if that makes sense) ((but the fmc is intriguing and I can’t quite place why yet, though the fact we haven’t had a pov chapter from her yet might have something to do with it 👀 she has a sense of knowing that I picked up on the first or second time she is noticed by the mc and I need to know more NEOW!!!))
I picked these up thinking they were a duology, and I am both disappointed and relieved to find out I was wrong! I eagerly await book 3, excited to see how this all ends but am struggling to be patient 😭

"Dark Tides" is a captivating sequel to "Dark Sands" that I simply couldn't put down… And I mean that! It’s the first book in years that I’ve stayed up late to read. J. S. Harman's writing is alluring and wonderfully descriptive, fully immersing you in these new worlds. The newly introduced characters are authentic and compelling, each bringing a unique perspective to the narrative.
The book is cleverly structured with smooth transitions between chapters, though the shifting perspectives can be frustratingly tantalizing, leaving you eagerly waiting to hear about different characters. The book masterfully explores the impacts of trauma and grief, evoking great sympathy for Tarlo and his friends.
Overall, "Dark Tides" is a truly wonderful read. It builds beautifully on the concepts established in the first book, leaving you on the edge of your seat, eagerly anticipating the final read of the trilogy. I honestly can't wait to get my hands on it!

It’s a sci-fi horror sequel that picks up right where Dark Sands (book one) left off—and honestly, I was hooked from the first page.
The atmosphere is one of the standout elements here. There’s a constant sense of tension, like something is always lurking just beneath the surface, ready to drag everything down with it. The pacing keeps things moving, balancing action with just enough quieter moments to let the characters breathe (and suffer a little).
Speaking of characters—they’re messy, layered, and feel real in a way that makes their struggles hit harder. The stakes aren’t just external; they’re deeply personal, and that emotional depth adds so much to the story.
I still have my suspicions about certain characters, and J.S. Harman had me guessing, theorising, and trying to piece everything together the entire way through.

Dark Tides by J.S. Harman is an astounding sequel to Dark Sands! Easily one of my favorite books of the year! If you are looking for mystery, horror, sci-fi, and a visceral human experience, pick up this series ASAP!
Tarlo, once again, forges ahead into the unknown and may not make it out the other side. There are some returning characters you know and love and all new interesting characters with vastly different lived experiences. Harman is masterful at making each character come alive and pull at your heartstrings.
I was particularly impressed by how the world opened up with some new POVs and information. I wasn't sure how the stakes would be raised and how this book was going to be bigger and more intense, but it blew me out of the water! It was creepy and heart pounding and a perfect sci-fi story! I loved the creativity and the way the story unfolds. Did I cry? Yes I did 😭
This book and series is for anyone and everyone! No matter what you like in books, you'll find it here! Did you recently enjoy Markaplier's Iron Lung movie? Then this is a perfect book for you! I'm on the edge of my seat for the next book! Five Stars! I cannot recommend this book enough! ⭐️⭐️⭐️⭐️⭐️

Review of advance copy received from Author
Thank you so much to J. S. Harman Firstly for writing this book. And secondly for being SO kind as to let me be one of the first to read and review it.
In this story Tarlo and a couple of other survivors from Cathos have gone through this strange portal to another planet. This time one that is all but covered entirely with endless sea.
I was very curious to see how Harman would handle an environment like this. How could we possibly survive underwater in just our spacesuits?
But what we find is that these black rocks they traveled through work as some kind of magnetic Bermuda triangle situation. So that the team who were stationed on this planet at the same time Tarlo and his crew were stationed on Cathos have set up a beacon device next to the cave entrance, and the crew are taken to Tuwia, a space station situation floating above the waters.
They are treated but still dealing with the emotional and mental repercussions as well as confusion of what they experienced on Cathos. But Tarlo chooses to venture into the sea with Tuwia's explorers. And the discoveries he makes while there are truly mind blowing....
This story sees our characters growing more in their relationships with one another. Exploring the idea of intimacy with one another and closeness. It's really nice to see this aspect being explored more within this book, as well as looking at the idea of rebellion and obedience to the original mission.
It is actual quite a political story looking back to those surviving on Cathos, and what has happened since Tarlo left. And also looks back at Earth and the repercussions of the families they left behind.
It looks at spin doctors, at the use of awards and honors within this spin doctoring and also at the idea of culture and race. One particularly interesting point looked at is how the original team from Tuwia are so cautious of those from Cathos. Both were from Earth only a couple years ago, but in that time they have developed their own experiences, knowledge systems, relationships, cultural type ideals that had me reflecting on the idea of racism and it's purpose in THIS world.
I absolutely loved this story. It had me even more on the edge of my seat than the first one, which was creepy with how hopeless the situation was, but this one we know the characters, they know each other, and Harman trusts his readers to remember whats in the first book. So he doesn't linger on reminders, but rather keeps the story moving.
The dangers in this book are INCREDIBLY different from those on Cathos, and it is ALMOST like you are reading a different genre with how different this story reads from dark sands.
The stories are so well connected though that they don't read as separate stories.
There IS a prologue and intro at the beginning which serves as reminders to what happened in the first book. But, refreshingly, reads as an entirely new part of this new story, rather than as annoying rehashing of old material. I loved how this was handled as it kept the books flowing one to the next.
Harman is an author who trusts his readers. Who loves his readers. And who shows deep respect for them. I've thoroughly enjoyed this series so far and CAN NOT wait to read book three. I'm on the edge of my seat already. But Harman assures me book three is in the pipeline and will be completed MUCH faster than these first two books. EEEEEEEEE I can't wait!

If you’ve seen my review for Dark Sands, you know that I was overflowing with love for JSH’s debut and his storytelling in general. That made Dark Tides one of my most anticipated reads of 2026 and let me tell you, it did not disappoint one bit. By nature, if Dark Sands was a 5/5, then Dark Tides has to be AT LEAST a 7/5. The story pulls you in immediately and does not let go. The pacing is, in my opinion, perfect. If I’d had the time, it’s entirely likely I could have downed Dark Tides in one go, but I enjoyed it in smaller sittings and found it delightfully easy to dive in each time. Stopping… that was a different story because I never wanted to put the book down!
The horror elements jumped out a bit more at me this time and I definitely felt the creepy crawlies in various points throughout the book. As someone who doesn’t read horror of any kind, I find this to be the most interesting phenomenon and a testament to JSH’s exceptional writing. In a way, you know something is coming, but the true dread is not knowing exactly what and realizing that no one can prepare for it. Exceptional… especially when things start hitting closer to home.
Which vaguely brings me to another thing I found super engaging in Dark Tides: the POVs are very wide ranging. You will see different pieces of the universe through at least half a dozen different characters’ eyes and there is a certain magic about that! It highlights JSH’s gift in writing characters that you can fall in love with in a few pages. I still remember the first time that was so masterfully and brutally pulled off in Dark Sands, and to see it happen again and again is nothing short of amazing. Authors (including me), take notes!
For the sake of the many potential spoilers that I would spew if I wrote a review the length of my Dark Sands one, I will keep this shorter and won’t be touching on plot elements, but let me just say. Wow. As a biologist, I LOVE the science, the different evolutionary perspectives, and the speculation that reaches beyond. My mind was absolutely blown along with the characters and although I am terrified (because, let’s be real… JSH, why are you so mean to your characters???), I am beyond stoked for the last installment and to see what else you come up with and where this story ends! It will undoubtedly be an epic conclusion that will live in the history books of indie releases that can absolutely stand up to the giants of traditional publishing.
The last thing, and something that I will always rave about in JSH’s work, is the sense of catharsis. The conflict at the heart of Dark Sands and Dark Tides is simultaneously like nothing any of us have ever faced and something we are all facing every day. I never thought I would relate so deeply, or that my heart would ache so much when reading these books. That’s to say nothing of the smaller, but just as impactful, challenges that individual characters go through. As he does in every sense, JSH sprinkles that diversity and inclusion throughout his works. I can guarantee that in reading this book, just like in reading Dark Sands, you will feel seen in some way. You will feel touched in some way. And you will look at the world in a different way. There’s a truly rare magic that JSH has perfected when writing about the human condition, and I will be following it for as long as he’s writing and I’m reading.

The second psychological experiment: same experiment, new variables, and the tides keep rising
Dark Tides feels like a continuation not just of the story, but of the experiment itself, same subjects, new environment, higher stakes.
This time, the setting shifts from infinite desert to infinite ocean. And somehow, the sense of isolation intensifies.
The hook here: the survivors are rescued… but not in a way that aligns with linear time or space. And, predictably (or perhaps inevitably), whatever they escaped may not have let go of them. "There’s something down there… in the deep…"
Where Dark Sands felt methodical and creeping, Dark Tides feels… unstable. Chaotic, fractured, displaced, both physical and temporal.
What really stands out is the evolution of the characters. In the first book, they felt like individuals sharing a mission. Here, they feel like a system that's interdependent, bonded through shared trauma. And interestingly, that bond extends to the reader as well. You don’t just observe their connection... you participate in it!
The author retains the logbook-style narration, but there’s a subtle shift. The “reports” feel less objective now, more emotionally contaminated. As if the act of recording data is no longer enough to maintain sanity.
The ocean setting is used brilliantly. There are moments of awe: observing alien marine life, the quiet beauty of an unfamiliar ecosystem. And then, almost immediately, that awe collapses into absence. Silence. Void. Inducing fear, the kind that's intense and irrational.
It captures something very specific: the fear of depth, not just physically, but psychologically. The idea that there are layers you cannot reach, cannot understand.
And once again, the emotional weight sneaks up on you. Decisions feel heavier. Loss feels sharper. The sense of inevitability is stronger.
By the end, the narrative fractures, time, space, and relationships all pulled apart at once. That separation hurts in a very real way. Not just because of what it means for the plot, but because of what it means for everything they’ve built together.
It’s a brutal cliffhanger. If Dark Sands was about discovery and dread, Dark Tides is about consequence and fragmentation.
I went into this expecting a sequel. What I got was a deepening of the same emotional and psychological spiral... and I’m absolutely here for whatever comes next.

Review of advance copy received from Author
Dark Tides completely pulled me in from start to finish. This instalment builds on the strengths of the first book and pushes them further, making the story feel larger in scale, darker in tone and even more powerful.
This time the story takes us to the ocean planet Alantia, and the setting is brilliantly realised. The vast stretches of water and the enormous beings hiding in the depths are described in a way that feels both vivid and deeply unsettling. There is a steady undercurrent of unease throughout, as if danger could rise at any moment. It captures the essence of sci-fi horror perfectly, with tension that never truly fades.
What impressed me most was the attention given to the characters. The narrative delves into trauma, anxiety and guilt, and shows how these experiences influence every decision they make. The relationships feel authentic and emotionally charged. Seeing connections strengthen, break apart and slowly mend after everything they have faced adds real depth. I genuinely cared about each of them.
The story moves quickly and wastes no time re-entering the conflict left behind in the previous book. It is intense, but the pacing worked very well for me. There are small pauses that allow you to catch your breath before the next wave of danger hits. The latter half in particular feels relentless in the best possible way.
I also appreciated how the world continues to grow. New questions arise, fresh perspectives are introduced and we begin to see how events ripple beyond a single planet. The links between these worlds are becoming more compelling with each chapter. References to characters and moments from the first book feel meaningful and well placed.
The conclusion raises even more mysteries while still delivering a satisfying close to this chapter. I finished the book feeling fulfilled, yet very eager to continue the journey.
Verdict: A gripping and atmospheric sci-fi horror sequel that strengthens its characters, broadens its universe and maintains powerful tension throughout. A solid 5 out of 5 read that makes waiting for the next book a real challenge.
A huge thank you to J. S. Harman for the eARC and for trusting me with this story. It was an incredible ride.

Review of advance copy received from Author
What point has suffering if there are none to bear witness? What can be seen if there are no eyes?
Just hours after the harrowing conclusion of Dark Sands, Tarlo and his fellow survivors of the Catal settlement find themselves on an entirely different planet--and, an entirely different time, discovering that a whole two years have passed since their disastrous escape from Cahros. They haven't a clue how they got there, and their own lack of explanation raises suspicions with the native Alantian colonists.
Alantia, a sister planet of Cahros but lightyears away, is comprised of nothing but an endless ocean. Like the desert hellscape from which they've escaped, it has two colonies: one, completely wiped out by an unknown force, and another with dwindling ranks that whittle down by the day. The Alantian colonists are growing antsy, waiting for their home to simply plunge into the depths beneath. In an effort to gain knowledge about the world and its hostility towards their presence, they deploy 3-man-crewed submersibles to scout and document everything they see--including the plethora of new species swimming in the dark waters. Tarlo volunteers to embark on one such dive, not only to satisfy his own thrills of new discovery, but to earn the trust of his hosts.
When a creature so massive that the submersible's navigation system mistakes it for the sea floor rears its ugly, invisible head--and one of Tarlo's unlucky crewmates is killed by blunt-force trauma of the thing merely bumping the vehicle--both the Cahran and Alantian colonists quickly learn that there is no room for animosity if they are going to survive.
Dark Sands set high expectations, and Dark Tides blew them out of the water (no pun intended). I was hooked from the very first sentence and the last left a gaping hole in my soul. For any horror, thriller, science fiction--or, any genre at all--lover who has not yet picked up this series, do yourself an immense favor and pick it up ASAP. I cannot wait for the next installment.

🔖 ARC Review
🙏 Thank you to J.S. Harman for the gifted eARC.
What lingered with me most after finishing Dark Tides was the same sense of awe and unease that made the first book so memorable—the feeling that the characters are only scratching the surface of something far larger than themselves. Oh, and that cliffhanger ending? 🤬
—
📖 Book Snapshot & Grip Factor
Continuing immediately from book one, we’re dropped back in and thrust into another unknown world. This new setting created a strikingly eerie backdrop—the endless water and sense of isolation added to the tension, giving the whole book a quiet, creepy vibe. That atmosphere was one of the story’s greatest strengths—there was a constant feeling that calm moments could shift into chaos at any time, but it still managed to balance the action with quieter character-driven scenes.
Just as in book one, the characters anchored the story. Their struggles weren’t only about surviving, but also about navigating grief, guilt, uncertainty, and the complicated emotions that come from relying on one another (and virtual strangers) in impossible circumstances. Those internal conflicts gave the narrative weight.
⏳ Looking back, what I remember most is:
• Feeling incredibly claustrophobic in certain scenes. 😬
• The way the broader mystery continued to unfold, revealing new pieces of the puzzle without ever losing its sense of wonder. I have NO IDEA what's going on, but that won't stop me from enjoying the ride.
👀 The Reality Check
It was a quick read—maybe too quick?—and I would have loved more. More time to explore this new world and get to know some of the new characters.
💭 Final Thoughts
Dark Tides was an immersive continuation that deepened the mystery, expanded the world, and once again proved that the heart of the story lies in its characters.
🔖 Tropes & Vibes
Hostile alien world + Cosmic mystery + Found family + Survival against the unknown + Sci-fi horror + Survival sci-fi + Death + Trauma + Grief + PTSD

significant improvement from the first book.
The author has absolutely leveled up their writing game. Not just in storytelling, but craft as well.
The science and character beats are all improved, the prose is far more confident (ocassional stumbles into overexplaining but it’s nowhere near as rough as the first.
The cosmic horror takes a bigger seat here, along with the intensity of “marine biology is metal AF”.
Tarlo continues to grow as a Protagonist, and the convenience of his ongoing survival is paid for in the blood of his elders.
A very solid continuation of the first book, but ends more or less similarly with a cliffhanger into another location, but unlike the first where it goes wild and we have no clue what’s happening, we get enough answers to continue the story,
Solid recommend for anyone looking for hard sci fi horror.
Some area I’d recommend to improve even further, the dialogue remains very professional and a little stilted. It’s nothing that ruins the story, but everyone speaks politely and formally with little of the natural inflections, errors, repetitions that are a part of normal speech.
There’s an interesting kind of mix of cosmic horror and ecological crisis being mixed here. All with a foundation of hard science that grounds the reader.
Another part is thr actual narrative. It still falls into omniscient, undercutting the tension, but I noticed it mostly near the end of the book implying to me that it’s editing fatigue. The narrative feels like it’s trying to be the “storyteller” but this creates distance between the reader and the protagonists. The story is far better and scarier when the narrative is from the perspective of the protagonists. Not that it’s bad, but just thinking of where I’d love to see continued improvement when the third book inevitably comes out.

Review of advance copy received from Author
There might be something out there in the deep, but between these pages I know rests the excitement of an amazingly scary horror book.
Harman has done it again!
I went into Dark Tides with high expectations, following the attention-grabbing and heartbeat-raising first book. Now, with glee, may I say that Dark Tides does not disappoint! In short, I can most certainly recommend it. Get it if this is your thing. You'd be helping an amazing indie author out and getting an amazing and tense book.
From the first moment, Dark Tides picks up right where Dark Sands left off. No time is wasted getting back into the tension and hopelessness of the situation, as we are reunited with beloved old characters and introduced to a fun cast of new ones.
While in a different setting with new themes and plethoras of creepiness, there is a familiar pace to and structure to the book. That said, this time we are following characters in completely different settings and situations, increasing the tension and drama even further.
Now, I must admit this book might be a bit faced paced for some. This is a current industry standard and I think Harman toes the line perfectly, giving just enough moments to breathe and let events sink in, or follow a different plot line, before being stabbed through the heart again (seriously, this Author is ruthless to his characters!). Still, don't expect a calm read going into this. Once you start, you're in for something. And once you've finished, you won't have the patience to wait for the third book.
At least I know I won't... The ruthless waves of Dark Tides certainly have me anchored to the Darkworlds series.

Dark Sands (book 1) pleased me because it was darker than I expected it to be. For the very same reason, I declare Dark Tides a bloody delight!
This story takes off running and gallops relentlessly from start to finish; I swear I could feel the stress and exhaustion of this crew of unfortunate survivors who just never seem to get a chance to sit down and take a breath.
I was struck by the (multiple) protagonists constant need to speedily re-orient themselves and adjust to the ceaseless parade of horrors they were facing without the opportunity to recover or strategise. Wow, is that ever relatable. The story masterfully reflects the way we have to keep swimming after personal disaster and trauma, often with no real sense of direction or even purpose beyond survival.
A well measured dose of dry humour peppered throughout the narrative of what is otherwise a pretty bleak and frightening story reminded me of the way we so often cope with terror- by cracking jokes in the dark. I thought this was particularly well balanced and relatable.
The cast have to trust each other to try to survive, often with no real precedent for doing so. When you're being hunted a long way from home, you don't have much choice but to stay close to whoever else is still alive!
Dark Tides is a fast paced and exciting sci-fi/ horror story but it's also deeply human and relatable. These characters aren't hardened space travellers, they're frightened, traumatised people clinging to each other in a storm that seems like it will never end.
Good stuff- looking forward to the next installment as much as I looked forward to this one.

Dark Tides is book two in the Darkworlds saga, and it picks right back up where book one, Dark Sands, left off. For the best reading experience, I recommend to read the books in order.
Tarlo's adventure continues, and from the desert of Cahros we are now wading through the waters of Alantia. And while things might seem different, the danger is still there, lurking where the light can't reach.
This book kept me on edge from the first page. We are now following three different worlds, all fighting for survival. The rhythm is incessant, the events keep pounding one after the other, and there isn't a safe harbour anywhere. There are multiple POV, and each one of the characters bring something different to the plate, a diverse view of the danger, of the inevitable, and of what might come to be.
I'm really enjoying this series. Every page is filled with tension that keeps building, and the climax always delivers, never letting things just go. And it's not just the present, but it's like we can almost see what's coming, the answer feels just out of reach, until something else comes along, and everything changes again.
If you are looking for a new sci-fi series to explore, this one is pretty fascinating, and with a fresh take on the new frontier. I can't wait for the rest of the story to unfold.

First of all, a huge thank you to J.S Harman for sending me an ARC of this book 💙🩵
Ever since closing 'Dark Sands' last year, I have been EAGER to pick up 'Dark Tides' because I knew it wouldn't disappoint, and it really didn't.
As with book 1, I was blown away by the way JSH builds tension and suspense, and how that knot in your stomach never quite goes away. It's the perfect mix of sci-fi horror. Yet again, you root for all the characters, I feel their pain and their loss and how inherently human they are. Watching their relationships bloom from book one to book two was beautiful.
The 'monsters' in Dark Tides are colossal and it's such a nice tie in to book 1's monster.
I love that we get to go back to Cahros and see what it has become, and how we get to visit Earth and see how what is happening on these planets is having an impact on Earth.
JSH simply has a way with words. When I read the book, it's like I'm watching it in real time, and one day, I hope I am watching it on a big screen because it holds that movie-esque quality.
I finished this book at 3am, I tossed my Kindle down.
I need book 3 in my hands.
J.S. Harman is an author to watch, to read, and to follow. I can't wait to see what else comes out of his brain. From the moment I read Dark Sands, I knew he would be an auto-read author - I don't have many of them, but books like this just stay with you. 🩵

Ever since closing 'Dark Sands' last year, I have been EAGER to pick up 'Dark Tides' because I knew it wouldn't disappoint, and it really didn't.
As with book 1, I was blown away by the way JSH builds tension and suspense, and how that knot in your stomach never quite goes away. It's the perfect mix of sci-fi horror. Yet again, you root for all the characters, I feel their pain and their loss and how inherently human they are. Watching their relationships bloom from book one to book two was beautiful.
The 'monsters' in Dark Tides are colossal and it's such a nice tie in to book 1's monster.
I love that we get to go back to Cahros and see what it has become, and how we get to visit Earth and see how what is happening on these planets is having an impact on Earth.
JSH simply has a way with words. When I read the book, it's like I'm watching it in real time, and one day, I hope I am watching it on a big screen because it holds that movie-esque quality.
I finished this book at 3am, I tossed my Kindle down.
I need book 3 in my hands.

Review of advance copy received from Author
This sequel is incredible!
If you're expecting things to slow down, our antagonists to catch their breath or for all the mysterious goings on to be solved - then think again. This book is breakneck, tense and will leave you gasping when you hit the last line.
Harman has this way of writing his characters that pulls the reader in, they are relatable, they have fears, they don't want to be brave but in the face of unimaginable horrors, they step up... or step out.
I'm in awe of his talent.
We find ourselves following multiple POV, our main character Tarlo, with the few remaining survivors on a new planet, Alantia, no land in sight and covered in a dark fathomless water that hides creatures that will haunt you each time you close your eyes. We also have eyes back on a crumbing earth, the world turning bleaker every rotation of the sun, and on Cahros where it all began, we follow the last group of terraformers on an abrasive and cruel planet, their mission seemingly futile.
And always, the black monoliths watch over it all.
I am so excited to see how this ends, where we'll be taken and who, in the end will survive... if anyone.
If you love:
- sci-fi thrillers
- sky-bases and deep mysterious oceans
- lovers under duress
- survival
- creepy undertones
- stressful situations
- terraforming new worlds
- all seems lost
- death and despair
- and maybe a smidge of hope...
Then you need to add these books to your tbr. I read this prior to official release date.

April 19, 2026Dark Tides by J.S. Harman is a science fiction novel that continues the story from the first book in the series. It follows the main character, Tarlo, as he tries to survive in a new and unfamiliar world after escaping the dangerous desert planet from before. At first, this new place, Alantia, seems safer and more advanced, but it quickly becomes clear that it has its own hidden dangers.
One thing I liked about this book is the setting. The author does a good job describing the new planet and making it feel real. The skybases and environment are interesting, and it makes the reader curious about what might happen next. There is also a lot of suspense, because even when things seem calm, you know something could go wrong at any moment.
Another strong part of the book is Tarlo as a character. He isn’t just dealing with new problems, but also the trauma from what he went through before. This makes him feel more realistic, and it helps the reader understand his decisions and emotions better.
However, some parts of the book can feel a little slow, especially when there are long descriptions. Also, if you haven’t read the first book, it might be confusing at times because the story builds off earlier events.
Overall, I think Dark Tides is a good sequel that keeps the story interesting and adds new challenges for the characters. It’s a good choice for people who like science fiction, survival stories, and a bit of mystery.

After the thrilling end of Dark Sands I could not wait to read Dark Tides, and I was very happy to receive an ARC of the latest instalment in the Darkworlds saga.
J.S. Harman has once again delivered another page-turner full of action, horror, and gut wrenching emotional journeys. Dark Tides picks up where Dark Sands left off and delves deeper into the mystery. I liked how the narrative was built through multiple character P.O.V.s and really enjoyed each P.O.V as they each added something unique to the story. The storytelling builds on the fast-paced sequences of Dark Sands, and there were many moments where I found myself gasping in horror.
I enjoyed J.S. Harman's exploration of the complex aftermath of trauma particularly the themes centered around survivor's guilt. The character's reactions are conveyed so poignantly I truly felt as though I was experiencing the same emotions as they were.
Dark Tides brings gives us so many answers and even more questions and I am eagerly awaiting to see where J.S. Harman takes this thrilling sci-fi horror series.
I highly recommend Dark Tides and the Darkworld saga! For anyone who hasn't read Dark Sands yet grab a copy of both books because you will not want to wait to see where the story goes.

What a perfect continuation from Dark Sands. And dare I say even scarier and more gripping?? Like I’m not kidding when I say I was hooked but I put it down and went to bed cause I was scared 😆 as usual I love his writing style. The storyline is spectacular I cannot say I’ve ever read anything like this and I’m so intrigued to see how everything will be brought along together. Nothing I can guess will come close to it for sure. The storyline has suspense, human emotions, horror, real truths, some interesting characters and of course the … I don’t know what to call them aliens? It’s so good.
Tarlo and the few surviving members have reached somewhere through the rocks, but where they don’t know. Because this planet has water. And their planet was not supposed to have water. So where were they? When they discover there’s people here too they thought they are finally safe. But.. vast oceans could mean things unknown hiding under the ocean. So are they really… safe?
The last revelation about the 5 planets and the little octopus thing was mind blowing I’m so keen for the next book! If you haven’t picked this series up already, what are you doing???

It picks up after the events of Dark Sands and throws Tarlo into a whole new environment. This time he ends up on an ocean planet called Alantia. The story moves from endless desert to deep-sea expeditions and floating skybases. It feels bigger and more intense than the first book.
What stood out most was how much darker and more emotional it gets. There’s a heavier focus on guilt, duty, and the cost of survival. Tarlo’s quiet resilience is still there, but the stakes feel more personal and the dread hits harder. The horror builds slowly at first. Then it drops off a cliff in a way that left me genuinely unsettled. The science and world-building stay clear without getting in the way.
It’s not a long book, but it packs a lot of tension and character work into the pages. The ending is another brutal cliffhanger that makes me want the third book right now. If you liked the atmosphere and slow-burn dread of Dark Sands, this one turns up the emotional pressure and the sense of isolation even more. A strong sequel that delivers on the promise of the first book. Super excited for the final part of the saga to come out. Dark Skies will be out August 2026.

ARC received from author. Sequel to last year's Dark Sands, Dark Tides is another side of the same character-focused sci-fi thriller coin. There's a duality between the two stories that I really enjoyed: the deserts of Cahros versus the ocean of Alantia; floating settlements versus deep sea exploration; microscopic creatures versus unfathomably large ones; the settlement they left behind that was all but decimated, and a new one where life is quiet, successful, and without incident... yet. It's like the galaxy rhyming. What the two books, and the two planets within, have in common is a deep disregard for human life. Continuing on from the first book, we see explorers become survivors, horrifying creatures, and more questions than answers on why they're out there alone with no contact from their people, why they feel they're being kept alive, and what's out there with them, in the depths... With new characters and new discoveries, it's an engaging follow up and I'm keen to see where the journey continues in the next book.

Well today i finished Dark Tides, the second instalment of the Darkworlds Saga, and it did not disappoint. Thankyou to J.S Harman for trusting the buddy group with our early copies to read.
What follows on from book 1 is, well, everything. I still don't trust anyone, i still have questions and the new setting is still eerie and bleak. I held my breath in Chapter 7 and i was heart broken again in Chapter 25, which i feel was a personal attack from the author himself after my heartbreak in Ch 25 of Dark Sands. I love how we got to see the characters develop and the very real emotions of guilt, anxiety and companionship that developed from their ordeal and being thrown back into survival mode.
We have been trying to connect dots, speculating hard, referring back to book 1 and making some very outrageous (but maybe plausible) theories. That my friends, is a great book if you, like me, love a real brain tickling read.
If you enjoy accessible sci-fi, i highly recommend picking this up. I will be sure to check in with answers after book 3. If i ever get them i guess.

Dark Tides by JS Harman is the direct followup to Dark Sands, a space exploration adventure beyond the great black…and an unknow planet unlike ours.
Unlike Dark Sands, which was a true pageturner to the core filled with the unknown, Dark Tides l had a slightly more political/emotional setting in the background.
Don’t get me wrong: still a true pageturner, still plenty of weird stuff happening but also some fingers pointed at upper management.
And again there were plenty of based-on-unbelievable-but-probably-true-science facts.
So, all-in-all: more real life relatable issues...
Because you can sort of expect what will happen after you read Dark Sands, Dark Tides is less surprising. That said; I still wanted to take a deep dive into the unknown and soak up all the creepy vibes this book had to offer!
I recommend this book to, well, readers of the first one, but also to people going for spooky vibes in space where desolation & feeling lost are important themes

Another incredible story from J.S. Harman - Dark Tides built upon everything Dark Sands promised, while heaping on further strife and suffering for characters you can’t help but care for.
I was absolutely enthralled with the watery world of Alantia and its mysterious depths. The story begins with a more tempered sense of adventure and discovery as the survivors of Cahros experience this new planet for the first time. Having read Dark Sands, I was on high alert for hints at the carnage that would come—and in this department the novel far exceeded my expectations.
Be prepared for a headlong rush in the second half, and some exciting throwbacks to beloved characters and their fates from book one. The ending hinted at so many more answers left to come about these worlds and their connections to each other, and I am on the edge of my seat waiting for book three!
