The Myrandia Cycle. Myrandia, #1

In a realm teetering on the precipice of a new, terrifying age, where arcane science births weapons of unimaginable power and the very fabric of existence can be unmade by a single, resonant note, destinies collide. From the gilded cages of treacherous courts, a young noblewoman, cursed with an unnervingly keen eye, uncovers a conspiracy that bleeds from the shadowed heart of her kingdom. In hidden laboratories, an ambitious alchemist forges a living defense, its wild and unpredictable song a desperate shield against the encroaching darkness.
Across burning deserts, an exiled sea captain, her own song silenced, navigates a cursed city of madness and ancient power, her quest for vengeance now bound to the tormented heart of a forgotten civilization. In the grand halls of a rival power, a master spy weaves her own deadly web, caught between shadowy allegiances as she uncovers threads linking a provincial alchemist's dangerous creation to the highest echelons of ambition.
And on a forgotten frontier, a hardened commander, abandoned by her king, battles an enemy armed with alchemical fire, only to discover a rot that festers deep within her own kingdom's command. As ancient prophecies stir and the Silent Song of a hidden people faces the discordant roar of a changing world, the Resonance Cascade was but the first deafening chord. The Rational Arts, once a promise of enlightenment, now forge instruments of annihilation.
Loyalties shatter like glass, alliances shift like desert sands, and the gyre widens. When the Silent Voice finally sings, will any be left to hear its song?
