The exiles trilogy contains the full text of three novels by Ben bova, XLS from Earth, flight of the XLS, and end of exile. Not one word has been added or omitted. Alas the word was United under one government. Utopia had arrived and its leaders were determined to crush anything that could upset the delicate balance. To maintain the status quo, the world government imprisoned several thousand scientists and their families and prepared and isolated orbital station where they will live out their lives in exile. But Lou, Christopher and the other scientists were born free and intend to remain soap. If the world government has no place for Earth's finest minds than they would escape to the Stars, and build a world where freedom was more important than security, where Liberty was life itself.
