Legion of the Damned (Legion of the Damned Series #1)

The first novel in William C. Dietz's acclaimed Legion of the Damned series...

There is one final choice for the hopeless—the terminally ill, the condemned criminals, the victims who cannot be saved: becoming cyborg soldiers in the Legion. Their human bodies are destroyed and they are reborn as living weapons. But when aliens attack the Empire, the Legion must choose sides.
