A young human girl grows up in slavery on planet Sidon. Her owners are malicious and violent. They are executed, however, for treason by their government and all the human slaves in their residence are returned to Earth for resale. Three Sidonian brothers buy many new humans to work on their farm. It is the largest Sunflower farm on Earth, so the newly acquired slave girl goes beneath their notice until a secret from her past reveals itself and ignites the known universe.
