Black Corrosion is part of a series but can be read as a stand-alone story. It is set in the future after a mass destruction. Those left are on a quest for survival amidst impending war.
The tale is filled with battles, espionage, war planning, and scientific discoveries. However, it also is about families, love, and loyalty.
The author creates vivid imagery and well developed characters. The details make you feel as if you are part of the action.
This is a great book for those who love fantasy or science fiction as it is a little of both. It is also great for those who like action.
This is the third book in Gurgu’s series after Pink Corrosion, and I really enjoyed diving back into this world. The cover itself caught my attention right away—it has that dark, dystopian vibe that perfectly matches the story inside.
The book follows Prince Geo Woodman as he prepares for his toughest challenge yet—facing Emperor Han the Great. Han’s army leaves nothing but destruction behind, and Geo, along with Princess Bree, has to step up as a leader while also trying to hold on to what’s left of their bond.
What I loved is that it’s not just non-stop battles. The writing style is fast-paced but easy to follow, and Gurgu also weaves in quieter, emotional moments that give the story more depth. You really feel the weight on Geo and Bree as they try to balance survival, leadership, and love in a collapsing world.
It’s the kind of book that pulls you in with action but keeps you invested because of the characters. If you like dystopian reads with strong characters, high stakes, and a mix of heart and grit, this one is definitely worth picking up.
For the Characters As Much As the Battles I picked this up expecting a fast-paced, dystopian war novel and while it definitely delivers on action, what really gripped me were the characters. Geo is such a compelling leader. He isn’t perfect; he makes hard choices, second-guesses himself, and struggles with the weight of responsibility. Bree, on the other hand, is stubborn, brilliant, and deeply human. The way she processes trauma while still finding strength through science and invention made me admire her more and more as the chapters unfolded. The story is full of battles, raids, and tense political councils, but the quieter moments are what I’ll remember most: Geo trying to be strong for others even when he feels broken, Bree pushing forward with her experiments despite nightmares of crucifixion, and the two of them finding rare moments of tenderness together. This isn’t just a book about fighting monsters and enemies. It’s about the small, fragile ways people hold onto hope in a world that’s falling apart. And that’s why I loved it.
Angel Stole the Show for Me Don’t get me wrong, the human characters are great but Angel, the flying creature, is the one who absolutely stole the spotlight for me. Gurgu writes with such intensity that she feels more alive than many human protagonists I’ve read elsewhere. Angel is fierce, terrifying, and strangely tender at times. The way she moves, perceives the world, and fights in the skies alongside Dreams and Nightmares is written with so much vivid detail, I felt like I was watching an IMAX battle unfold above my head. What I loved most is that Angel isn’t just a gimmick or a monster thrown in for coolness. She has a perspective, a voice, a place in the story’s emotional landscape. Her scenes are brutal, yes, but also strangely beautiful especially when she observes the humans below with something like compassion. If you like your post-apocalyptic stories with inventive, nonhuman points of view that actually feel fleshed out, Angel alone makes this book worth it. But the good news is, everything else around her is just as strong.
Moral Ambiguity That Feels Real One of the aspects I admired most about this novel is how it refuses to paint morality in black and white. Survival in a broken world is complicated, and Gurgu doesn’t shy away from that truth. Sometimes the “right” choice costs lives. Sometimes showing mercy leads to more destruction. The book doesn’t hand you easy answers, it makes you sit with discomfort. I found myself questioning what I would have done in Geo’s position, or whether Bree’s decisions were reckless or necessary. It’s rare for a book to pull me into those thought experiments, but this one did again and again. That moral ambiguity made the story feel authentic. In real life, especially in desperate situations, there are no clean solutions. Watching the characters wrestle
Wow! What a strong finish for this trilogy! This is science fiction at its best. It has everything—adventure, a sense of wonder, love, and friendship. This entire trilogy was top-notch. Bravo!
Costi Gurgu’s Black Corrosion, the third instalment in his Corrosion series, expands the scope of his dystopian world while deepening its thematic resonance. Set in a future Earth devastated by the Black Rain—an ecological catastrophe that transforms water into a corrosive gel—this volume follows Geo Woodman, crown prince of the Silkers, as he confronts Emperor Han the Great, whose advancing armies threaten what remains of civilisation. Gurgu’s world-building skillfully merges apocalyptic science fiction with dark fantasy, introducing shape-shifting entities such as Dreams and Nightmares alongside vivid environmental imagery. Set in Torono, a city reduced to ruin yet still a focal point of resistance, the novel interlaces personal stakes—Geo’s partnership with Bree and their impending child—with a geopolitical struggle that could determine the fate of the planet.
The novel’s layered structure accommodates a wide range of subplots, from political manoeuvring to the enigmatic phenomenon of children capable of projecting themselves beyond Earth’s pink-clouded sky. This element signals a speculative thread in which human evolution—whether physical, mental, or both—becomes a counterpoint to the immediate devastation of war. Bree’s scientific inquiries into the risks and potential of this astral travel provide a conceptual bridge between survivalist urgency and long-term adaptation. Gurgu also retains his talent for arresting, surreal visuals: cocooning superhuman beings, colossal stag beetles, and dawn creeping over shattered glass all serve to reinforce the strange beauty of his post-cataclysmic landscape.
What distinguishes Black Corrosion from many contemporary dystopias is its measured infusion of hope into an otherwise relentless world. Though scarcity, violence, and loss pervade the text, the possibility of renewal—whether through political victory, biological transformation, or cosmic migration—undercuts the fatalism often associated with the genre. The multiple narrative strands converge in a way that feels thematically coherent, leaving space for future developments without compromising resolution. As a continuation of Gurgu’s series, it demonstrates both an expansion of scale and a refinement of craft. A great fun read, and a must for genre enthusiasts!
If you're into dark, gritty sci-fi with a twist of horror, Black Corrosion is your next must-read. There is a lot going on with stories of people just going through it all, struggling to survive, dealing with crazy tech, and facing some seriously messed-up situations.
The world creation in this book is top-notch, blending cyberpunk vibes with psychological thrills. The characters are complex and flawed, making their struggles feel real and relatable. It's not just about surviving in a dystopian future; it's about what it means to hold onto your humanity when everything else is falling apart.
There are moments that will make you pause and think, and others that will have you flipping pages faster than you can blink. It's a rollercoaster of emotions, and Gurgu doesn't let up.
If you're looking for a book that challenges you, makes you think, and keeps you hooked from start to finish, Black Corrosion is it. Just be ready for a wild ride through a world that's as dark as it is intriguing.
A Book That Stays With You From the very first page, I knew this was going to be something special. Gurgu’s description of the pink, corrosive sky, “like an old man’s brain,” is such a disturbing yet poetic image that it lodged itself in my mind and set the tone for the entire story. This isn’t just a post-apocalyptic adventure; it’s a meditation on survival, morality, and what it means to remain human when the world itself seems against you. What impressed me most is how real the world feels. Torono is not just a backdrop; it breathes, groans, and corrodes right alongside the characters. Every ruin, every corrupted cocoon, every toxic breath feels authentic. It made me feel like I was actually walking through the rubble with Geo and Bree, fighting for every scrap of safety. I finished this book weeks ago, and I’m still haunted by certain passages. It’s rare to find a novel that combines sharp, cinematic action with such aching humanity. This one does. Five stars without hesitation.
Science and Survival Intertwined One of the things I appreciated most about this book is the way science and survival are woven together. Bree isn’t just a passive character or a love interest she’s a scientist at heart, even in a world that’s crumbling. Watching her tinker with armor coatings, work out designs for children’s protective suits, and try to apply knowledge to desperate situations gave the story a fresh angle. Too often, post-apocalyptic stories focus only on brute strength or luck. Here, innovation is just as important as courage. Bree’s experiments don’t always work, and sometimes they put her at risk, but they feel authentic to who she is, a woman who refuses to stop searching for solutions, even while fighting her own nightmares. It made me think: in a real end-of-the-world scenario, it wouldn’t just be soldiers and leaders who mattered. It would be the thinkers, the experimenters, the ones who try to build something out of ruins. That’s what makes this story not just exciting, but inspiring too.
Political Intrigue Done Right I honestly didn’t expect the political side of this book to be so good. Most post-apocalyptic novels focus solely on survival and combat, but Gurgu manages to weave in real political tension that adds layers to the stakes. The war councils, the spies hidden in plain sight, the clashing of egos and loyalties it all felt believable and, frankly, chilling. One of my favorite sequences was the council where tempers flare and suspicions of betrayal bubble up. Nobody is painted as one-dimensional; even allies have their own agendas, and sometimes survival means making morally gray choices. That felt honest and made me care about the outcome beyond the battles. For readers who enjoy the strategy and manipulation of something like Game of Thrones but set in a devastated, toxic world, this book scratches that itch. It’s tense, layered, and shows that sometimes the deadliest threats don’t have claws or wings they sit beside you at the council table.
Action Scenes That Rival Cinema If you’re an action junkie like me, this book will not disappoint. The Night Raid sequence and the battle at Gard Bridge are some of the most thrilling pieces of writing I’ve read in a long time. Gurgu has a gift for describing combat in a way that’s both crystal clear and completely immersive. You hear the clatter of weapons, feel the weight of rubble underfoot, and practically taste the smoke in the air. What’s even better is that the action never feels hollow. Every battle has emotional stakes tied to it. Whether it’s protecting the Cave, saving children, or holding the line against overwhelming odds, you’re invested in the outcome because you care about the people involved. I found myself holding my breath during entire chapters. And when I put the book down, it felt like I’d just stepped out of a movie theater after watching something epic. That’s how alive the action feels on the page.
Worldbuilding That Seeps Into Your Bones The ruined city of Torono and the wider world in this book are unlike anything else I’ve read. Gurgu doesn’t just throw in a few dystopian clichés and call it a day. He builds a world where the very air is a threat, where the sky itself has turned into something grotesque, where corruption spreads through cocoons and walls alike. It’s vivid, unsettling, and yet strangely beautiful in places. The descriptions are never just for show. The environment actively shapes the characters’ choices, their fears, and their hopes. When Bree suits up to work outside, or when Geo has to strategize around the toxic hazards of the landscape, it feels practical and real. This is what post-apocalyptic writing should be: immersive and unforgiving. By the time I finished, I felt like I had actually lived in this world for a while and honestly, part of me never wanted to leave.
Bree’s Story Broke My Heart For me, Bree is the heart of this novel. Her backstory is painful, the trauma of crucifixion, the weight of memory, the nightmares that haunt her and yet she’s also one of the strongest characters I’ve read in recent fiction. What struck me most was how Gurgu writes her resilience. It isn’t perfect or pretty. She stumbles, she struggles, she doubts herself. But she keeps pushing forward. Her scientific work isn’t just a plot device; it’s a way of reclaiming control over a world that tried to break her. I loved how her mind keeps working, how she finds meaning in problem-solving even when it’s dangerous. There’s something so moving about the way she embodies both vulnerability and strength at the same time. By the end, I realized that while the battles are spectacular, it was Bree’s personal fight against her own fears, against the scars of the past that left the deepest mark on me as a reader.
A Leader Who Feels Real Geo might be my favorite character simply because he’s written so honestly. Too often in fiction, leaders are either flawless heroes or completely incompetent. Geo is neither. He’s strong, yes, but he also wrestles with doubt, with guilt, with the burden of making decisions that might cost lives. That tension makes him believable, and it makes his victories all the more satisfying. The book doesn’t shy away from showing the impossible choices he has to make. Do you risk civilians to win a battle? Do you spare an enemy at the cost of your own people’s safety? These are the questions Geo faces, and they’re written in a way that feels grounded and painfully human. Reading his chapters reminded me that true leadership isn’t about always being right, it's about carrying the weight of mistakes and still moving forward. And that’s exactly what makes him a character worth rooting for.
The Children Will Break Your Heart The children in this story were the most unexpected surprise for me. In a book full of battles and strategy, I didn’t expect the smaller moments with the Cave kids to leave such a mark. Their abilities, like teleportation, are fascinating, but it’s their vulnerability that really got to me. The way the Cave community tries to protect them, teach them, and even build space suits for them shows such a beautiful contrast to the violence happening outside. One of the most touching moments was when Jon tries to be a teacher figure, giving them not just knowledge but also kindness in a world that doesn’t have much of it. It reminded me that hope often survives in the youngest among us, even when everything else is falling apart. I didn’t expect to cry during a book about corrosion and battles but the children’s subplot caught me off guard and gave the story its deepest emotional weight.
: Strange Creatures That Feel Original One of the highlights of this book for me was the introduction of the Dreams and Nightmares. I’ve read a lot of post-apocalyptic and dark fantasy novels, but rarely do the nonhuman creatures feel as vividly imagined as they do here. Gurgu doesn’t just describe what they look like, he gives them tactics, behaviors, and personalities that make them feel like actual forces in the world rather than plot devices. The aerial battles involving Angel, Dreams, and Nightmares are some of the most cinematic sequences in the entire book. You can practically see the sky tearing apart with motion. And yet, these creatures aren’t just spectacle. Their existence raises questions about evolution, corruption, and survival in this poisoned landscape. It’s not easy to create something truly original in this genre, but Gurgu managed to surprise me more than once. That’s rare, and it’s one of the reasons this book stands out so strongly. er
: Smart Worldbuilding Through Science I’ve always been fascinated by the intersection of science and storytelling, and this book absolutely nails it. Bree’s experiments with armor coatings, protective gear, and even children’s suits are described in such a way that they feel both plausible and emotionally charged. These aren’t abstract inventions; they’re born out of desperation and love for the community. What impressed me most is that these details never felt like info dumps. The scientific elements are embedded naturally in the story, always tied to the characters’ needs. For example, when Bree is testing a lightweight defensive coating, it’s not just a random experiment it’s directly tied to the survival of people she cares about. That grounded approach made me believe in the world even more. It reminded me that survival in extreme circumstances isn’t just about brute force; it’s also about innovation and persistence.
Hope in the Darkest Places This is, without question, a dark book. The violence, the decay, the sheer despair of the landscape can feel overwhelming at times. But what makes it powerful is that, even in the midst of all that ruin, there are flickers of hope. The community dinners, the lessons given to children, the attempts to rebuild even a small piece of normalcy, those moments hit me harder than any battle scene. I found myself deeply moved by the way the Cave tried to create a school for the children, or how small acts of kindness ripple outward even when survival is the top priority. These moments don’t erase the horror of the world, but they provide a counterbalance that makes the story feel more real and more human. For me, that’s the heart of this book: it shows that hope can exist even when everything else seems broken. And sometimes, that hope is the most radical act of all.
: Young Heroes With Real Weight The children in this story aren’t just background characters or symbols of innocence, they're active participants with agency, power, and vulnerability. I loved how their teleportation ability was integrated into the plot, not just as a cool trick, but as something that affects strategy, safety, and even the community’s future. What stood out to me was the respect Gurgu gives them. They’re not written as miniature adults, nor are they helpless props. They’re kids curious, scared, brave, reckless and that authenticity made their chapters some of the most engaging. The effort to create protective suits for them shows how much they matter to the adults around them, and how their survival represents a kind of hope for the future. It’s rare that I find myself as invested in the child characters as I am in the adults, but here, they’re every bit as compelling.
This is a gripping continuation of the dystopian saga, following Prince Geo Woodman as he faces his most perilous challenge yet: the ruthless Emperor Han the Great. In a world ravaged by the loss of water and resources, Gurgu weaves a tale of survival, resilience, and courage. Geo and Princess Bree step into their roles as leaders, confronting both personal struggles and the looming threat of destruction. What makes the book compelling is its balance of fast paced action and emotional depth. The battles are tense and vivid, but just as powerful are the quieter moments where characters wrestle with loyalty, hope, and sacrifice. Gurgu’s writing captures both the brutality of a collapsing world and the enduring strength of those fighting to preserve it. Fans of dystopian and dark fantasy will appreciate the way Gurgu builds on the themes from Pink Corrosion, offering not just thrilling conflict but also thought provoking reflections on leadership and humanity. This is a bold, unforgettable entry in the series that leaves you eager for what comes next.
Dark, Poetic, and Disturbing What makes this book stand out for me is Gurgu’s writing style. It’s brutal when it needs to be, but there are also passages of real poetry that cut deeper than gore ever could. The chapter describing the Black Sky ritual and the vanished high priestess is one of the most unsettling things I’ve read in a long time. It made my skin crawl and my heart ache at the same time. This balance of horror and beauty is hard to pull off, but it’s exactly what makes Black Corrosion such a memorable read. I wasn’t just turning pages for the action (though the action is excellent); I found myself rereading sentences because of how they were crafted. It’s rare that a book can be both page-turning and thought-provoking, but this one achieves it. Disturbing, yes but also hauntingly beautiful.
A Weekend Page-Turner This book had me hooked from the first chapter. I planned to read a few pages before bed, but instead, I stayed up way too late and ended up finishing it over the weekend. The pacing is sharp, with just the right balance of suspense, action, and character moments. Every chapter ends in a way that makes you want to read just one more and then suddenly it’s 3 a.m. What I loved most was how there was no filler. Every scene moves the story forward, whether it’s a heart-pounding battle or a quiet moment between two characters. I’ve read plenty of books where I skim through sections waiting for something exciting to happen, but that never happened here. If you’re looking for a book that will completely take over your weekend, this is it. Be warned: once you start, you won’t want to stop.
A Story of Balance What impressed me most about this novel is the way it balances different tones. On one hand, you have huge, cinematic battles with terrifying enemies. On the other, you have intimate, almost fragile moments of humanity, conversations between friends, stolen moments of tenderness, quiet reflection. Both feel equally important, and that’s what makes the story work so well. I especially loved the chapters focusing on Jon, Stev, and Pi. These weren’t just filler characters; they brought warmth and perspective to the story. Their interactions reminded me of how even in the worst of times, people can still laugh, teach, and support each other. It’s rare to find a book that can make me grip the pages in suspense one moment and then smile softly the next. This one did. That balance is why I’ll be recommending it to everyone I know.
A Villain You’ll Never Forget Han the Great is one of the most chilling villains I’ve come across in recent years. He isn’t just evil for the sake of it, he's an ideologue, an emperor who truly believes in his ruthless mission. That makes him all the more frightening. When he issues orders or when his soldiers enforce his will, it’s clear that his cruelty isn’t random; it’s systematic, planned, and terrifying. What I appreciated is that Gurgu doesn’t make him cartoonish. He’s powerful, intelligent, and charismatic in his own twisted way. That’s why he feels so real and so dangerous. The scenes where his writ is carried out gave me chills because they showed just how far his influence extends. A hero is only as strong as the villain they’re up against, and Han pushes every character to their limits. He’s the kind of antagonist you’ll hate but also never forget.
Pacing That Pulls You Along One of the hardest things for a writer to nail is pacing, but Gurgu gets it just right here. The story knows exactly when to hit you with high-octane battles and when to slow down for quieter, character-driven moments. That rhythm kept me completely engaged. For example, right after a harrowing fight sequence, there’s often a pause where characters reflect, argue, or simply share a meal. Those slower beats aren’t filler; they're the moments where we see who these people really are. Then, just when you’ve caught your breath, another wave of danger crashes in. It feels like living inside the ebb and flow of survival. The effect is that I never once felt bored, but I also never felt exhausted. This isn’t just nonstop action; it’s a well-structured journey that respects the reader’s attention and emotions.
Tactical Brilliance for Strategy Lovers As someone who enjoys military history and strategy games, I found the tactical side of this book incredibly satisfying. Gurgu clearly put thought into how battles would unfold from troop placement and siegecraft to improvised barricades and clever use of terrain. The Gard Bridge battle, in particular, felt like watching a real strategy map come to life. What’s impressive is that these details never bog down the story. They’re integrated seamlessly into the action, so you’re learning about defenses and flanking maneuvers while your heart is pounding over whether the characters will make it out alive. If you’re the kind of reader who likes to imagine how you’d plan a defense or whether you’d order a retreat, this book will scratch that itch. It’s gritty, clever, and always grounded in real stakes.
A Love Story Woven Into the Ruin I didn’t expect the romance to feel as genuine as it did, but Geo and Bree’s relationship became one of my favorite parts of the book. Too often in action-heavy stories, romance feels tacked on or forced. Here, it’s organic, built through shared trauma, mutual respect, and quiet moments of tenderness. What I loved most is that their love doesn’t make the world feel any less dangerous. If anything, it raises the stakes. Every battle becomes more intense because you know they’re fighting not just for survival, but for each other. Their relationship humanizes the story and gives it an emotional center that makes the victories sweeter and the losses more devastating. In the middle of all the corrosion and chaos, their bond felt like a reminder of why people keep fighting for connection, for love, for something worth holding onto.
Dialogue That Rings True Sometimes in books like this, dialogue can feel either too stiff or too modern for the setting. Not here. Gurgu’s characters speak the way real people under pressure would speak terse when the stakes are high, sarcastic when they need to cut the tension, loving in those rare quiet moments. The council meetings, for example, are full of personality. You can hear the frustration, suspicion, and passion in every exchange. On the flip side, the intimate conversations between Geo and Bree are tender without being cheesy, and the banter among the secondary characters feels natural and unforced. That authenticity in dialogue pulled me deeper into the world. It made me forget I was reading a book and feel like I was eavesdropping on real people fighting to stay alive. For me, that’s one of the biggest signs of strong writing.
Structure That Shapes the Journey One thing I didn’t expect to enjoy so much was the structure of the book itself. The chapter titles and the way the story is divided aren’t just cosmetic choices they really guide the emotional arc of the novel. Titles like The Nine Thresholds of Sleep or The Night Raid set the tone for what’s coming and frame each section in a way that feels purposeful. It gave me the sense that I wasn’t just moving through random events but traveling across carefully chosen thresholds, each one building on the last. The architecture of the story is as deliberate as the worldbuilding, and that’s what made me feel so anchored even when the action was chaotic. I’ve read many books where I forget the chapter titles the moment I turn the page. Here, they lingered, almost like echoes of the themes themselves. That’s a rare accomplishment.
