Shadow and Light (Ash and Aether #4)

Kaster Nexis is the predator the gods forgot to kill. A solitary dragon of the Ash Wastes, he lives by a clinical, savage code: kill anything that crosses his border.

But the rules of his isolation are shattering.

For the first time, Kaster isn’t just defending territory—he’s guarding a woman who makes his teeth ache with a primal, predatory need he can no longer calculate away.

Soreia Grave is an Anchor witch dying by inches. Her magic is the only thing that makes death stick in a world of divine regeneration, but every use burns away the months she has left.

She’s spent a lifetime running from the vision of her own end, only to find herself at the side of a dragon who treats her survival as a strategic imperative.

Her only hope for a future isn’t a cure—it’s an unwanted union that will change her fundamental nature forever. The gods are done with mercy.

They have unleashed a divine poison designed to unravel Soreia’s bloodline and leave Kaster alone in an infinite war.

As the ice-scarred plains fracture, Kaster must cross the only line he ever feared: Claim the mate. Anchor the ending. Kill a god.
