Lifeline — Kevin J. Anderson

In shock and grief the last remnants of the human race watched from space as the holocaust of war raged across the face of the Earth. Now the future rested in the hands of three fragile space colonies: Aguinaldo -- The Philippine L-5 colony whose brilliant biochemist engineered a limitless supply of food. Kibalchich -- The Soviet space exploration platform that harbors a deadly secret. Orbitech 1 -- The American space factory whose superstrong weavewire could be a lifeline to link the colonies -- or a cutting-edge weapon of destruction. As allies, they could unite to rebuild a better world. As enemies, they could destroy mankind's last hope for survival.
