A fierce and imaginative epic, Black Corrosion marks the powerful third installment in Costi Gurgu’s Corrosion series—an unflinching meditation on power, survival, and what it means to remain human when the world around you is not. This is a multifaceted novel featuring apocalyptic landscapes, drugs, space exploration, violence, rebirth, depression, collusion, and pandemic—yet none of it feels superfluous. Every element is essential, woven into a richly layered narrative that explores the fragile boundaries between hope and despair. In Black Corrosion, Geo Woodman, the newly elected ruler of Silkers, alongside his loyal wife, remaining family, and close friends, tries to find his place in a corrosive dystopian world inhabited by Dream and Nightmare creatures, all the while struggling to prepare for the final battle against Han the Great—a powerful, genocide-driven warlord. Gurgu creates incredibly smart and humane protagonists who see war not as a heroic spectacle, but as a humbling phenomenon in which survival is never guaranteed and the cost of victory is never clean. Against all odds, they strive for happiness in a world where hope is scarce. Though centred on battle preparations, Black Corrosion is just as much about the internal battles each character faces. The psychological toll is relentless and the stakes are intense, uncovering the characters’ deepest fears and doubts, dispersed at times by a kind word, a well-placed question, or a moment of wisdom. In this way, Gurgu captures the human condition with extraordinary nuance, fusing dystopian world-building with emotional clarity. Structurally, the novel is a triumph. Gurgu’s deftly constructed train of chapters introduces one theme at a time, then pivots seamlessly to the next, making a compound plot interesting and easy to follow. The narrative unfolds like a war log spliced with internal monologue, balancing action, and introspection. Gurgu also shines in moments of surreal world-building—alternating between the oddly delicious meals of the new era and nostalgic cravings for the lost flavours of the old world. These contrasts enrich a universe that feels both foreign and eerily familiar. For readers of sci-fi, horror, and philosophical fantasy, this is an immersive, genre-defying experience that will challenge and captivate in equal measure. While it follows the arc set in Green Corrosion and Pink Corrosion, Black Corrosion confidently stands on its own as a sophisticated, emotionally resonant journey. Moments of gore and existential unease are offset by quiet beauty, brutal truths, and glimpses of awe—in the stars, in the silence, in what we choose to fight for. Both brutal and beautiful, Gurgu’s Black Corrosion is a masterclass in speculative fiction and a must-read for anyone ready to stare down the end of the world. —CANREADS BOOK REVIEW
