Auremia is sinking. Its rulers already know which part of the city they intend to sacrifice.Taren Voss is a lowborn repair apprentice with an inconvenient talent: he can read the strain in stone, hear danger in failing pipes, and recognize the cracks nobles would rather hide beneath white plaster. His warnings are ignored—until the capital's Founding Day square tears open, an ancient crown rises from the lake, and an impossible doorway appears beneath the city.With only seven days before an emergency law seals off the royal center and abandons the lower districts, Taren receives a forbidden descent warrant. Joined by Elowra Quayle, a relentless waterway manager, and a small royal escort, he must enter the Inverted Foundation: a colossal dungeon of shifting gravity, moving bridges, drowned corridors, silent sluices, and ancient machinery built to preserve the crown at any cost.Every chamber is connected to the people above. Every repair could trigger a deadlier collapse. And the deeper Taren descends, the more he is haunted by impossible memories of concrete tunnels, red warning lights, and a flood he should never have witnessed.To save Auremia, a repairman dismissed by its rulers must outthink the system holding the city together—and prove that survival does not have to mean choosing who gets left below.A fast-paced standalone epic fantasy adventure featuring a witty underdog hero, deadly dungeon puzzles, magical engineering, class conflict, high-stakes survival, and a desperate race to save a sinking city.Can Taren repair a capital designed to protect the powerful first, or will Auremia's shining towers survive only by burying everyone beneath them?
