Diahann Sparks, a Black, plus-size, autistic, and agender homebody, hid in a world of pastels, pastries, and pretty illusions. Then their younger sister was raped and driven to suicide by a bunch of rich frat boys who walked away free. The law failed, but Diahann will not.

Their first attempt at revenge almost ends them when they meet Vesper Payne, a Black, plus-size bisexual vigilante serial killer known as the Black Mamba, with a taste for blood and a heart of ice. Diahann is soft edges and steady hands. Vesper is sharp teeth and darker appetites. They should have nothing in common.

Except for the same targets and a hunger for justice that will not be denied.

Together, they carve a path through the privileged and corrupt, their bond fueled by violence, need, and something far more dangerous: love. But when the killing ends, will their thirst for blood be enough to keep them together, or will the darkness that binds them tear them apart?

A brutal, twisted tale of vengeance, desire, and love that will carve you to the bone.
