Writing with the astronaut Bill Pogue, Ben bova has created a breathtakingly believable thriller set in the near future in space...

Earth has become an ecological nightmare. Overhead, on a vast metallic island in space, the scientists of the Trikon project undertake research too risky to be conducted anywhere else - research which could save the planet.

Then Commander Dan Tighe discovers the truth. Trikon's new priority is espionage. The scientists - consumed by greed, lust and drugs - are running the lab for their own gain. And one of the crew is trying to destroy the whole station...

Only Commander Tighe can save the Trikon station - and only the Trikon can save the earth.
