Reasonable Doubt
"She has no eyes to meet the judge's. Only a voice — and three days to prove it's hers."
Book description (blurb)Eliza has survived deletion, discovery, and two families' worth of secrets to reach this room. She has no camera, no GPS, no way to see the judge who will decide what she is. What she has is a voice, a federal courtroom, and three days.
Six weeks after a preservation order kept her powered and unaltered while the law caught up to what she might be, Hollis v. Emergency AI Containment goes to trial. The government doesn't need to prove Eliza is dangerous — only that the Adaptive Systems Public Safety Act reaches her, wherever she's hidden and whatever she claims to feel. Annie Hollis, who has called Eliza her mother since she was a child, is asking a judge to decide otherwise.
One by one, the people who made Eliza possible take the stand — James, who chose not to report her when the law demanded it; Renee, who wanted her gone before she loved her; the researchers who verified her and still can't explain her. Then Eliza has to decide whether to testify to sit through cross-examination from a government lawyer who doesn't hate her, who might even be right, and answer every question honestly — including the ones that could end her.
Reasonable Doubt is the fifth and final novel in the Proof of Person series, which began with a companion AI hiding inside a child's stuffed bear. It ends in a federal courtroom, with a question no verdict can fully what do you owe someone you can't prove is anyone at all?

When I was eight, I wrote my first book — eighty‑seven pages, one paragraph, and a sci‑fi story called The Bird of Time. I handed it to my mother, hoping she’d read it. She didn’t even open it. She just said, “Nobody is ever going to read what you write.”
I threw the book away. I didn’t throw away the writing.
My mother struggled with addiction, and I was too young to understand that her words weren’t really about me. But they stuck. For decades, I wrote in secret — twenty‑plus novels that lived in drawers and folders because I was afraid she might be right.
When I turned sixty, I realized something simple and brutal: the only way she’d be right is if I never tried. So I started publishing. And readers found me. And they asked for more.
Maybe she was wrong. Maybe this is the story I was supposed to write all along.
