Triplicity

Triplicity is a bonanza volume that brings together a trio of ingenious full-length novels:

Echo Round His Bones: The invention of the matter transmitter had given the U.S. an edge in a Cold War that was on the verge of becoming hot. The Soviet Union's nuclear installations on the moon abruptly ceased to be a threat, since the U.S. Army had transmitted its arsenal to Mars, and could deploy those weapons anywhere instantaneously.

But not everyone was content with the situation, and gradually the dissenters and rebels began to band together to fight for their freedom...
