Alpha Centauri or Die!

Alpha Centauri, the nearest star to the Solar System - only 4.3 light years away. To Kirby and his followers it meant freedom - freedom from the tyranny and repression of Earth's dictatorship. But that freedom would have to be earned - the flight to Alpha Centauri would mean five years jammed in the belly of an obsolete spaceship, five years of praying that the food supply would last, five years of fighting off the Government ships sent out to intercept them.... And if they did manage to reach the unknown planets that were their goal, what would they find? Freedom? Or a fate more terrible than any they could have faced on Earth?
