Plot summary

As a child, John Worthy lost his father, killed by the Federation. Eighteen years later he enlists as a starship lieutenant aboard Starship One, a prototype warship that can destroy planets. The Federation governs nine worlds, Old Earth among them. On Terra Nostra, a Federation planet with a large rebel population, three rebel ships attack his vessel and he destroys them. Old Earth's rebels refuse to cooperate with the Federation, and its Overseer orders the planet destroyed. John mutinies against Captain Savage rather than carry out the order. Rebel gunships damage Starship One, and John and the crew come down on Old Earth, where the rebel leader Xarsis and her daughter Jolli urge him to join them.
