Subtraction (Unabridged‪)‬

Revenge is subtraction.

In the alkali flats of 1869 Colorado Territory, Clara Kane counts. Seventeen names. Seventeen men who burned her parents alive and left her and her brother for dead. Half-Chinese and orphaned at ten, Clara has spent twelve years turning grief into geometry: every bullet drop, every wind drift, every heartbeat between shots. The mathematics don't lie. They never do.

Now the last of her targets are gathered in the desert city of New Rome — a fortress where General Titus Creed has raised marble walls, a colosseum, and an empire built on stolen ground. One final night. One perfect count.

But when her brother reappears after twelve years — alive, disguised, and working for the man who destroyed them — Clara's precision begins to fracture. The math changes. So does the mission.

What remains is a woman who has counted everything except the cost of becoming the thing she hunts.

"A bracingly sophisticated but highly entertaining tale that doesn't take itself too seriously." (Kirkus Reviews)
