What Waits After the Heart Stops

She volunteers where people go to die.
In hospital corridors heavy with silence and last breaths, she listens to stories, holds trembling hands, and learns the shape of grief before it arrives. And always, watching from the edges of the room, cloaked in shadow and inevitability, stands Death himself.
No one else can see him.
He does not speak to her. He does not acknowledge her. He simply appears wherever life is thinning, collecting souls with reverence and restraint. Yet every time she senses him near, dread coils with longing. An attraction she knows she should not feel. A presence she knows she should not want.
When their paths finally collide, the universe begins to fracture.
As Death breaks ancient laws to protect her, time falters, lives linger too long, and fate itself starts to unravel. Drawn together by something neither fully understands, they discover that love between the living and the eternal is not forbidden because it is impossible, but because it changes everything.
And as her body begins to change in ways no mortal should survive, she is forced to ask a question no one has ever answered:
What waits after the heart stops... when death is no longer the end?
