What happens when mercy has no off-switch?

ER nurse Naomi Thorne has learned to live with loss. Some patients survive. Some don’t. You do your best, you document the outcome, and you move on.

Until a dying man presses two strange stones into her hand… and whispers, “Make it matter.”

That night, Naomi separates them.

She isn’t in her kitchen anymore.

She’s beneath freezing lake water, reaching for a drowning woman.

The stones don’t give her power. They pull her into disaster—moments before death. Car crashes. Falls. Fires. Every time she separates them, she’s thrown into another life-or-death crisis. Every return leaves her weaker.

Bruises she can’t explain.
Exhaustion that won’t fade.
A growing obsession she can’t confess to anyone—not even her husband.

Because saving strangers is one thing.

Choosing when not to save them is another.

As the rescues escalate and the physical toll mounts, Naomi begins to realize the truth: the stones aren’t asking for heroism.

They’re demanding sacrifice.

Mercy or Nothing is a gripping supernatural medical thriller about life, death, and the dangerous line between compassion and control.

For readers who love high-stakes psychological suspense with a supernatural edge.
