Ancillary Justice

A consciousness once distributed across thousands of networked bodies is reduced to a single body. What was a starship and its corps of repurposed soldiers becomes one human frame, walking among the people of the empire that did this to her, working slowly toward revenge against the immortal ruler who is herself distributed across thousands of linked bodies and may be fighting a civil war against herself.
