This is one of the most important marketing tools. I've drafted a description that hooks the reader, introduces the core conflict, and highlights the unique elements of your world.
In an empire powered by the blood of captive gods, a single spark of divinity can either save the world or burn it to ash.
The sky fractured on the night they captured the last goddess. For nineteen years, the Solarian Empire has known peace, its cities illuminated and its armies empowered by the divine essence harvested from imprisoned deities. This is the world Mira has always known-a quiet, gray existence as a servant in the Grand Temple, hiding the dangerous secret of the storm that stirs beneath her skin.
When a city-wide ritual to detect hidden divine power exposes her, Mira is captured and conscripted into the very force that hunts her kind: the Godkiller Corps. Thrown into the brutal fortress of Divinity's End, she must learn to weaponize her own nature to survive.
Her trainer is the enigmatic Commander Darian Shadowbane, the man who captured her mother and bears a heavy, hidden burden of his own. As Mira navigates a treacherous world of military discipline and political intrigue, she discovers that the official history of the Godfall is a lie, and the Emperor's plans for the coming solstice threaten to consume what is left of the divine, plunging the world into an age of absolute, singular control.
Caught between a burgeoning resistance and the unyielding power of the Empire, Mira must embrace the heritage she has always feared. She is more than just a deity-born; she is a key, a weapon, and the last hope for the forgotten gods. But to free them, she may have to sacrifice her own humanity.
