Standalone
The Third Voice by Emily Hartstone, cover
The Third Voice
Who Decides What the Machines May Do to You

Argues that the ordinary protections a person holds when another person acts on them, the right to know who decided, why, and what it takes to reverse it, disappear the moment a machine acts instead. Written for a general reader rather than a technical one, and standing outside the Runtime Authority Series. Closes with The Third Voice Charter, published openly as A Bill of Runtime Rights.
