The Law of Five is a lie.

Rin Vesper is a Surgeon for the Order of St. Suture. They carved a raven into her spine and called it salvation. It was preparation.

Now the raven is gone. Ripped out by an Apostle with six grafts who sang twenty thousand people into drowning.

Rin has three grafts left: wolf, bear, wolverine.
No balance. No pack. Just war.

The Order promoted her anyway. Gave her a cell. They're watching through the glass, waiting for her to break-waiting for proof the Law of Five was right.

They'll be waiting forever.

Because the First Surgeon had twelve grafts. And he's still out there.

Suture & Sin is for readers who want:

- Grimdark Biopunk: Genetic grafts, surgical magic, body horror
- Military Fantasy: Cells, Orders, wars fought with claws
- Female Antihero: A surgeon who cuts deeper to keep from going Feral
- Cursed Techniques & Moral Decay: Supernatural powers, escalating consequences, and hard choices.

Book 1 of the Order of St. Suture series.

For fans of the dark biopunk horror of Tokyo Ghoul, the cursed-power systems of Jujutsu Kaisen, and the gothic intensity of The Locked Tomb.
