Three Worlds to ConquerPoul Anderson
Jupiter – where no man could live – but where men had strange allies... and stranger enemies!
Ganymede – where human settlers lay helpless under the guns of a spaceship captained by a madman!
Earth – freed from a planet-wide tyranny, but faced with total destruction from space!
The destinies of these worlds were strangely linked – and in the hands of a man sentenced to instant death!
