D.K. Landtroop
Best-Selling Author of The Fortifier & Broken Universe Series
D.K. Landtroop writes stories that trust the reader as much as they challenge the characters.
Known for The Fortifier and Broken Universe series, Landtroop blends humor, grit, and sharp intelligence into every world he builds. His characters don’t stumble through exposition—they fight, laugh, and think their way through it. Whether rebuilding civilization after an apocalypse or navigating the impossible return from another world, his protagonists act like real people thrust into worlds of danger, wonder, and consequence.
Landtroop’s stories balance adventure, fantasy, and mystery with grounded realism, never talking down to readers or wasting their time. Each book rewards those who pay attention—filled with small clues, clever callbacks, and quiet moments that matter later. Fans praise his work for its believable worlds, slow-burn intensity, and razor-edged humor.
When he isn’t writing about survival, strategy, and the often absurd brilliance of humanity, he’s probably plotting the next story that keeps readers up too late, muttering, “Just one more chapter.”
What if the Isekai’d hero came back—with secrets, debts, and all his power stripped away?
Kyle Sangster ruled a magical realm as its near-divine emperor, forged in battles against the nine armies of hell and bound by pacts with gods who summoned him. After a decade of epic adventures, he found a way home to the parents and friends he loves. But he wakes in his 17-year-old body, fresh from a year-long coma, in a hometown far too curious about him.
High school. Worried parents. Zero magic. Once a world-ruler, now a regular teen—his legendary skills now mere fragments. His old foes led demon legions; here, they run banks and score touchdowns. His parents, crushed by debt from his care, need him now more than ever. Yet his return may be unraveling reality, awakening magic in his friends and stirring forces only he can see.
With shadowy threats closing in, Kyle must rebuild his strength, outsmart cunning enemies, and protect his family while guiding a world on the brink of transformation.
Witty, raw, and fiercely original, Broken Universe flips portal fantasy on its head—where a hero’s choice to return may have broken reality.
Surviving the first days of the apocalypse, William is a wreck and hiding in an attic. The daily acid storms, floating elementals, and bizarre mutated animals are the least of his problems.
The reality-warping apocalypse has rules and a system much like those in video games. To survive, he must learn how the new uncooperative system works, choose a class without any real knowledge of what it does and create a place safe from the spawning horrors.
For William, staying alive isn’t enough. He will need to bring other survivors together and build a fortification large enough for all of them if he ever wants to strike back at the things that took everyone he loved. That is if he can ever gain control over himself and finally get any answers to what has happened.
Equal parts strategy, psychology, humor, and grit, The Fortifier strips the genre down to what matters—real people surviving the unreal. It refuses every worn-out trope and rewrites the playbook into something entirely its own: intelligent, human, and impossible to forget.
CONGRATULATIONS!
You have survived...
Weeks of pulling humans together and using his class to build a new safe home were shattered when everyone should have been celebrating.
For William, building wonders comes easily, but his class needs constant fuel, and the knowledge he and all humans need to survive stays woefully absent or must be hard-won. The assistants have more knowledge to give, but even they are perplexed by the events transpiring.
Now the world is changing again, and potential new friends and enemies will appear. But can he trust any of them when they are here trying to survive as well?
The only way forward is to keep leveling and learning as much as possible while saving as many people as he can.
Will the shattered races be friends that can answer questions or enemies seeking to take what William fought to create?
