The Gentle Giants of Ganymede

THE END OF EXILELong before the world of the Ganymeans blew apart, millennia ago, the strange race of giants had vanished. No one could discover their fate, nor where they had gone, nor why. There was only a wrecked ship abandoned on a frozen satellite of Jupiter. And now Earth's code and scientists were there, determined to ferret out the secret of the lost race.And suddenly, spinning out of the vastness of space and immensity of time, the ship of the strange, humanoid giants returned. They brought with them answers that would alter all Mankind's knowledge of human origins in startling revelations from the past that would have biologic reverberations to be at this time. . .
