By Her Own Hand: Book 4 In The Last Immunity

The outbreak has a name now. So does the woman they need to stop it.

Mara Hale has spent her life being studied, contained, hunted, and renamed by people who believed her body mattered more than her consent. Now the illness born from what Vale Sanctuary did to her is spreading beyond every wall built to hide it. It’s crossing state lines, collapsing families, and forcing the country to confront a truth its institutions are desperate to manage before anyone can fully understand it.

Evan Danner knows the pattern is widening. Naomi Crowell knows the systems will protect themselves first. Lydia Grant knows the science may arrive too late. And Mara knows what all of them are trying not to say:

The answer may still be inside her.

As hospitals fill, public language softens, and government officials begin drafting policies around a living woman’s body, Mara is offered every version of protection except the one thing she has been denied from the beginning: the right to decide what happens next.

But this time, no one writes the terms for her.

By Her Own Hand is the devastating fourth book in the Last Immunity series — a literary thriller about consent, survival, institutional power, and the terrible cost of becoming the only person who can save the world.
