A killer's oath. A child's fate. A kingdom teetering on the edge.
Louis is a master of shadows—an assassin whose blade has silenced countless enemies in the name of duty. But his next mission demands a sacrifice that chills him to the bone: eliminate the ruthless Baron Tybalt du Mamel and his entire bloodline…

…including a single, innocent child.

With the last Duke of Etendulat dead and no heir brave enough to face the brutal Trials of Dusang, the Empire’s heartland bleeds. Ambitious rivals circle, eager to seize control, and chief among them is Tybalt du Mamel—a baron whose ruthless ambition could plunge the Empire into chaos. Whispers of dark, forbidden forces swirl around his rise, but no one dares to name the danger.

Trained from birth to obey, Louis is dispatched to end Tybalt’s deadly aspirations before the Empire’s fragile peace shatters. But as he stalks his prey, Louis uncovers a conspiracy far more insidious than he imagined—a web of treachery that stretches into the highest echelons of power.

Caught between duty and conscience, Louis must confront his own red lines. Can he condemn an innocent to save a kingdom? Or will he defy his masters and risk everything to protect a life? As shadows gather and loyalties fracture, Louis must decide where his true path lies… even if it costs him his soul.

Hidden Blade is the first gripping installment of the Sangwheel Chronicles. Dive into a world of intrigue, loyalty, and the brutal cost of survival—where every decision cuts deeper than a blade.
