Voidwalker

Rate this book
The universe of Antherieon is a vast, layered expanse where reality fractures into realms that drift between what is seen and what has been forgotten. Though each world breathes on its own, they are all bound by something greater :
A silent thread of fate woven by time.

The Eôṅśa, beings of immense power, once shaped these realms, guiding their tides and maintaining the fragile balance between light and shadow. But even they are bound.
They can tilt the scales, but never remake them. The true power to create from nothing, or unmake reality entirely, was lost long ago, sealed within the Primordials buried beneath the silence of ages.

But silence does not last forever.
The seals are weakening.
Something older than light has begun to stir.

As the first whispers of the void seep back into the realms, the ancient balance begins to unravel. Shadows stretch longer and storms remember to rise.

From the edge of ruin, a war awakens.
One that will not just decide the fate of worlds, but the truth behind them.

This book drops you into a world on the edge of ruin — realms breaking apart, shadows stirring, and monsters creeping back into the light. It’s dark, tense, and full of that looming sense that something bigger is about to shatter.

What really worked for me were the characters. Selara and Elliora are absolute standouts — fierce, layered, and unforgettable. Caelum brings that mysterious, broody energy that makes every scene with him magnetic. And the romance? A true slow burn. Every glance, every moment of softness, carried so much weight that when the payoff came, it was worth the wait.

The action scenes were another highlight — fast, intense, but never losing that emotional thread. They had a cinematic quality, like watching a battle unfold on a huge screen, full of shadows, storms, and magic colliding.

Now, for a little honesty: while I adored the world, the characters, and the story itself, the writing style wasn’t completely my taste. That’s purely personal preference, and it didn’t stop me from enjoying the journey. The heart of the story, the emotion, and the imagination absolutely shine through.

And obviously it ends with a cliffhanger!!!

The core premise and central concept are undeniably intriguing, immediately pulling the reader into a narrative that promises something fresh and compelling. The story establishes a fascinating foundation that captures your attention from the opening pages, hinting at a deep, sprawling lore that makes you want to keep turning pages just to unravel its secrets. It is a book that clearly has a lot of ambition and a strong hook, making it an engaging ride for anyone who loves stepping into an original speculative universe.

However, the narrative execution stumbles a bit, for me, when it comes to the pacing and the passage of time. Throughout the book, time feels incredibly fluid, making it difficult to gauge exactly how much time is passing between individual scenes or how long the characters have actually known each other. Because the chronological markers are so vague, the emotional development between the characters often feels like it is making massive leaps without the necessary grounding. Relationships suddenly feel intensely deeply rooted before the narrative has fully built the emotional foundation required to make those bonds feel completely earned and believable.

This sense of detachment extends to the world-building, which currently operates at a very high level. While the foundational elements of the universe are captivating, the details remain somewhat sparse and surface-level for the time being. The setting is shrouded in a dense layer of mystery, leaving you with far more questions than outright connections to how this world truly functions. Instead of feeling frustrating, though, this ambiguity actually works in the book’s favor to spark curiosity; it leaves a strong desire to see this lore expanded and fleshed out in future installments.

🍵 Final Verdict
Voidwalker is a captivating and mysterious start to a story that shines brightest in its unique concept and atmospheric potential. While the fluid pacing and rapid relationship progression occasionally weaken the emotional impact, the sheer intrigue of the world makes it well worth the read. It is a solid recommendation for readers who enjoy high-level universe building and are excited to dive into a story that leaves them eager for more answers in the next book.

Selara has been stalking the realm, destroying void creatures while she slips through the shadows like a wraith. Elliora is mouring the loss of her parents, and set to destroy the one who caused them to disappear, along with the help of her close companion Caelum. At a crossroads, they realise they must work together to uncover their own secrets, and save the realm.

*****

I was genuinely hooked on this from the first few pages. The writing style is descriptive and beautiful, the third person narration is done flawlessly and melds the characters and their thoughts and feelings so well.

The world is described in bits and pieces that slowly build the realm they exist in, with the authors clear passion for the story she wrote is laid out in the long and detailed chapters. All of these do a beautiful service to the story, however the length of the novel is it's downfall.

If this was double the length, there would be time to develop relationships and plotlines that instead felt incredibly rushed. There's so much care put into the rest of the story and prose, that it was jarring to have characters meet, hate, and then profess feelings all with a rapid timeline, with very little externally occurring to cause those changes. The affection felt unnatural and rushed, despite a long journey on the road that could have described those feelings going forward, instead of telling us they existed.

I also found the points in the plot to be incredibly interesting, especially the traumatic ones before the end, but instead of letting the tension and stress simmer and draw out so the reader can really feel it, they were almost immediately resolved within pages of them occuring. Between that, the repetitious battle scenes spaced closely together, and Caelum consistently choosing to speak in another language the reader couldn't understand, it left too many loose strings that wouldn't make this a favourite read.

Despite all of the above, this author has phenomenal potential. If they chose to write a much longer fantasy novel I would absolutely read it.

Thank you to the author Brenna Kasey for sending me a copy of this book. All thoughts and opinions are my own.

Somewhere around 3.5 stars. This was a really interesting idea! The writing style was not necessarily my cup of tea. I didn't always see the character relationship developments and transitions between scenes sometimes felt jagged, but I thought the concept was super cool, original, and well thought out. I appreciated the idea of the Eonsa (I would love a pronunciation on this!! I've been saying Awnsha in my head). The characters were interesting and had nice nuances to them. It was a nice change of pace for the girl to have the shadow powers instead of the overused "shadow daddy" trope.

The void creatures were a cool monster to be fighting, I wish there was more expansion on them! It felt a little battle heavy sometimes with not as much differences between the battles as I would have liked, but I liked the BBEG and hope there is more development with him in future books.

Overall I enjoyed the story and I will check out the next books, and I also look forward to seeing this author develop as this was a nice debut book!

Right away you are thrown into a realm that is full of darkness and ruin. Something is always lurking in the shadows, a monster creeping in the background, and void portals opening out of nowhere. I enjoyed the world building and character development because it gave me the illusion as if I was there right along the way in the story. Selara and Elliora are fierce FMC’s, but man Selara can be stubborn and she tends to like to push Caelum. Caelum definitely gives off that tough and bored energy and he wants to keep Selara safe. There is tension building between the two of them and the romance, it’s a slow burn for sure. The battle scenes were some of my favorite! They were high action and intense, kept me engaged and wanting more. I also loved the scene where they were in a town and Caelum was playing with his powers and the lightning and the children loved it, just something about it made me see him in a foster and less broody side.this book needed on a cliffhanger and I can’t wait to dive into the second book to see how the story continues.

This has so much going on! It's great! I really like Selara, Caelum and Elliora. They are all strong individuals and are pivotal to the storyline. I like the magic aspect to this and the void portals.

I like the amount of imagination there can be with magic and unknown creatures, shadows and portals. So good!

Selara has healing powers, which when you live in a world where things can come through a portal and attack, a healing ability is very useful!

I feel sorry for Caelum at times, although a big, strong guy, he still has feelings; obviously, but when Selara gets returned, he's in two minds whether to comfort her or let her process first. Knowing what he's just been told, will time heal the wounds?

Straight into the next book!

Thank you so much Brenna for gifting me a copy of this book! All thoughts are my own.

Voidwalker is a fast paced and immersive fantasy read. The world is dark and often felt like a dream. There were moments I wish could’ve been expanded upon and some scenes that felt a little rushed. But I loved the writing style and the plot twists. The plot keeps you engaged because of the POV from Orinthe the Soulseeker.

Fantasy-Romance? Me? Never… Until Now!

Okay besties, hear me out—I never go for romantasy. Like, mythical realms and third-person POV? Not usually my jam. But "Voidwalker" by Brenna Kasey pulled me in like a Caelum-sized gravitational force and wouldn’t let go. Selara and Elliora? Total powerhouses. Caelum? Mysterious and broody in the best way. The build-up? Necessary. The romance? Slooooow burn—but worth every smoldering glance and emotionally tender moment. There is a spicy scene, but it is not graphic, but what’s there is gorgeous and beautifully written.

Now, let’s talk fight scenes—because yes. Think Avengers meets ancient gods and goddesses. Epic battles, rich world-building, and an author who knows how to craft tension and action without losing that emotional thread. Even with third-person (which usually isn't my thing), Brenna’s writing made it so immersive, I forgot my preferences.

And yes, it ends on a CLIFFHANGER. I need book 2 like yesterday.

If you like a slow-burn, god-tier power struggles, and emotional tension that simmers? Yeah... this one's got your name written in stardust.

I am surprised more people aren't talking about this book, this is top tier fantasy reading. It has some romance, but I think it is more fantasy. The mythical realm world-building was so good, the romance is a very slow burn. The characters have strong unique personalities. The fighting scenes were "movie-like" for lack of a better term. They were really well done. The tension and emotional turmoil were felt. It does hang on a cliffhanger so I will be getting my hands on book 2 asap.

Voidwalker drops you into an imaginative world of divine beings, creeping darkness and ancient mythology from the very first page. The premise is compelling, and once the story found its footing, it was hard to put down.

The three central characters are the heart of the book with a dynamic that is charged and entertaining. They form a reluctant alliance between personalities that could not be more different, each carrying secrets and wounds that slowly surface as the story progresses. The writing style conveys emotional subtext well, letting what isn't said carry just as much weight as what is. The action sequences are dynamic and seamless, and the threat driving the plot has a satisfyingly ominous weight to it.

My biggest point of criticism is the dense collection of invented words. I found myself keeping notes from the start to help keep track of it all. From realm names, titles and character names to an entire ancient language that appears throughout with inconsistent translation, it was a bit harder to simply sink into the story the way I wanted to.

In the end it was worth pushing through because the story that emerges is atmospheric, emotionally engaging and sets up what could be a very compelling series. Fantasy readers who enjoy deep world-building and slow-burn character dynamics will find a lot to enjoy.

*I received a copy of this book at no cost, though not in exchange for a review. All opinions are my own.*

I think this might be the start of my new favorite series. It's labeled as fiction, but it had me asking real questions the whole time ... what does justice actually mean? What is the cost of power? The eonsa seem like gods, but they're flawed, raw, and deeply human. I felt connected to one of them in particular. Identity plays a huge role in the story, and it really sticks with you after the final page. If you've been through anything, this story will make you feel seen.

I quickly fell in love with all the characters in this book. With how well developed they are it's hard to believe this is Brennas first book! I can't wait to see how the rest of the story unfolds I just hope my heart can take it! If you are looking for a well thought out dark fantasy story this is a must read.

4.5 ⭐️

This tale drags you straight into divine carnage through the eyes of Orianthe the Soulseeker, the very vessel doomed to witness a goddess lose everything in a single breath.

The legend begins when Eôňśa Elliora is left orphaned by cosmic betrayal, she’s forced to seize the throne of a fractured pantheon before her tears can even touch the ground. The realm of gods becomes hers to command… or burn?

Then we’re hurled into the mortal realm, where humans are being hunted, picked off like prey, by the ravenous horrors of the Void. And from that blood-soaked soil rises Selara, abandoned, memory-scraped, and furious. Every attempt to uncover her lineage ends in a hollow ache, and the gods’ silence has carved her into something sharp. While her town is devoured, she does what the divine refuse to do: she fights back. She refuses to let the weak die while the heavens avert their gaze.

And just when the worlds can’t take another fracture, Eǒňśa Caelum storms in— right as destiny, doom, and desire collide. Their paths are too deliberate, too intertwined to be coincidence. The fates clearly have an agenda… even if none of them are willing to speak it aloud.

If you want epic fantasy energy trimmed into a devastatingly tight package, this one delivers. No fluff. No filler. Just battles that shake realms, a slow burn that smolders between every clash, and twists that refuse to let you breathe. Sure, I’d devour a 400-page version without blinking—but what’s here? Chef’s kiss.

The pacing snaps. The world-building is lean but lush, woven so seamlessly you barely notice how deep you’ve sunk until you’re ankle-deep in divine politics and Void-touched terror. Every setting feels perfectly sculpted for its arrival. And every character arc lands thunderously.

But fair warning: that final cliff? Sheer drop. No railing. Good luck.

I’ll be clawing my way into book two the moment I’m able.
