With former air force major Trent Calloway's marriage ruined in the aftermath of his psychic spying, he wants to forget about his past, especially the tragedy that changed his life when he was involved in a government remote-viewing project. Unwittingly, Calloway and his team were being drugged during his remote-viewing sessions, and now, the drug is causing ever increasing side effects in himself and other government spies he worked with - and their psychic abilities are still expanding at frightening rates. The unknown drug he and the others took has bound them together in a deadly psychic nexus, a "PSI net".
Now Calloway must fight for his life - and his sanity - as he battles for the security of the United States and its people.
