The Clockwork Heart

In the soot-choked city of Brassreach, survival belongs to those who can bend the rules—or the laws of nature.

Eirene Calder is a gifted gearwright who keeps the city's broken machines running long after they should have died. But when her beloved sister Lyra's failing heart slips beyond saving, Eirene breaks the greatest law of all: she forges a heart of brass, crystal, and forbidden Maker-Aether… and places it inside Lyra's chest.

Lyra awakens healed—stronger, brighter, impossibly alive.
And wrong.

The machines begin to listen to her. The city engines shift to her rhythm. Metal bends to her will. And somewhere in the ruins of a forgotten age, something ancient wakes and remembers the world it once ruled.

Now the Council hunts them. The city trembles. And the skyship captain Cassian Vale may be the only one reckless—or desperate—enough to help them escape.

But Lyra's new heart is no mere device. It is a key. A beacon. A voice whispering of unity and obedience. As the bond between sisters is tested by power, guilt, and impossible love, Eirene must decide:

How much of a soul can be traded for a miracle?
And what happens when humanity is no longer the one beating the drum of destiny?

The Clockwork Heart is a lush steampunk fantasy of forbidden science, found family, and the fragile, beautiful terror of loving someone who is no longer entirely human.
